What is the coefficient of kinetic friction between the block and the plane in terms of the angle of the incline? (Hint: do any forces acting on the block change direction during its travels?)

Every decision is important in life, such as studying for a higher profession, who will be the future fiancé, what car to buy or which house checks every item off our list. Moving away to another state could be caused by a variety of reasons including personal long term goals or the opportunity of a better job.
In the book of Exodus (34:5-6), God very clearly revealed himself when Moses received the Ten Commandments on Mount Sinai. God Almighty stood alongside Moses and proclaimed, "The Lord, the Lord, a merciful and gracious God, slow to anger, rich in kindness and fidelity."
Moses was so impressed by these qualities that he bowed low and asked God to please accompany the people on their journey through the desert.

Researchers at the Massachusetts Institute of Technology (MIT) have created a new structured gel that can rapidly change color in response to a variety of stimuli, including temperature, pressure, salt concentration, and humidity. The gel could be used as a fast and inexpensive chemical sensor. These environmental sensors could be used in food processing plants, where it would indicate if food that must remain dry
has been exposed to
high levels of humidity.
To do that, they started with a self-assembling block copolymer thin film made of alternating layers of two materials, polystyrene and poly-2-vinyl-pyridine. The thickness of those layers and their refractive indices determine what color light will be reflected by the resulting gel.
By keeping the thickness of the polystyrene layer constant and altering the thickness of the poly-2-vinyl-pyridine layer with external stimuli such as pH and salt concentration, the researchers were able to change the gel's color in fractions of a second.
The MIT team is also working on a gel that changes color in response to applied voltages.

Aaron Goldstein: We're Not in 1980 AnymoreRoundup: Media's Take
Aaron Goldstein writes from Boston, Massachusetts.
For months, conservatives have been likening the conditions of the 2012 presidential race to that which saw the election of Ronald Reagan in 1980. The American Spectator's own Jeffrey Lord proclaimed that President Obama could be beaten handily "because the past four years really have been Jimmy Carter's second term."
Victor Davis Hanson of National Review Online put it this way:
What does 1980 tell us about 2012? Barack Obama, like Carter, can run neither on his dismal four-year stewardship of the economy nor on his collapsing Middle East policy.
Hanson went on to write:
The winner probably won't be decided by old video clips, gaffes, or even campaign money, but by turnout and the October debates -- depending on whether incumbent Obama comes across as a petulant Carter and challenger Romney appears an upbeat Reagan. As in 1980, voters want a better president -- but they first have to be assured he's on the ballot.
Well, Obama did come across as petulant in the debates while Romney was upbeat. And yet it wasn't enough. At the end of the day, despite Obama's dismal economic record and an ineffectual Middle East policy, his well-oiled organization turned out his vote and Romney could not. Romney could not break through in key states like Pennsylvania, Wisconsin, and Michigan nor could he put Ohio and Florida back in the Republican column.
And yet Obama didn't win on turnout alone. He won because America has changed. We're not in 1980 anymore...

Authorities did not immediately identify the child who died at Schlitterbahn Waterpark in Kansas City, Kansas, but state Rep. Scott Schwab and his wife released a statement saying it was their son Caleb Thomas Schwab.
"Since the day he was born, he brought abundant joy to our family and all those he came in contact with," said the statement, which asked for privacy as the family grieves.

I know all about the ups and downs of working a project like this and IMHO, you guys have knocked it out of the park. When you're pushing a game's engine to the limits, it becomes a bit insane trying to walk that fine line between what can be done and what you envision.
My hats off to you JONES, and all of the people that put time in on AP. It's one of the best game mods around and the only one I can think of outside of PR that squeezes as much nectar out of this old engine. Great work and best of luck with your future endeavors.

Thanks so much for visiting my shop! I hope you enjoy my fabrics :) If you would like this print customized (resized, or colors changed) please ask, I am happy to attempt to make any changes you require. I always suggest, especially if you are purchasing large amounts of fabric or wallpaper, that you order a swatch first! Sometimes colors can shift depending on your monitor. Colors can also vary a bit depending on which fabric you choose to print onto. Sometimes I have a swatch I can photograph and email to you, but it may not always be on the same type of fabric you need. So just to be safe, Spoonflower and I recommend you swatch first!

Yet Another Win For Darwinism; Barney DFA'd
Survival of the fittest and all, and Darwin Barney has just been naturally selected off of the Cubs 40-man roster. So Emilio Bonificaio is activated and Barney gets DFA'd, with Alcantara and Bonifacio both in the starting lineup tonight. Barney will end his Cubs career with over 2000 PA's (holy shit..really?) and a place in the Hall of Cubs Punch Lines. I'm sure a stand-up guy and all and his glove work was spectacular, but he was the hitting equivalent of the sad trombone. But on this day, we celebrate his Cubs career, let's take a fond look back.

Yeah, I never had a problem
Yeah, I never had a problem with Barney. He just couldn't hit well, hit with power, or run particularly well. But he'd be a nice 25th man to backup second and short on a contending team. He plays great defense and good fundamental baseball. And seems like a good clubhouse guy, hustles, etc. I would have actually rather seen Bonifacio let go than Barney, but its a six and a half-dozen situation to me; and I assume they made this move thinking about potential trades from here on out.
Also, I would love to just watch those highlight clips of Barney. I'd spend 10-15 minutes watching them all. And I don't mind a few adds (even though the banners and sidebars are already covered in them); but I sure as hell won't sit through a 15-second annoying McDonalds commercial between EACH ONE. MLB.com is terrible.

Rangers placed C Geovany Soto on the 15-day disabled list with a right groin strain.
Soto lasted just three games on the Rangers' active roster. He missed the first three-and-a-half months of the 2014 season following knee surgery and will now likely be sidelined through mid-August. Robinson Chirinos will again serve as the primary catcher in Texas.

With a team that can hit, Darwin would be a great addition

The Cubs can release, trade,
The Cubs have ten days to either release, trade, or outright Darwin Barney to the minors, but because he was not replaced on the 40-man roster by another player when he was Designated for Assignment, the Cubs could also choose to return Barney to the 40-man roster and option him to minors.
Because it has been more than three years since he made his debut on an MLB 25-man Active List, Optional Assignmemt Waivers would be required before Barney can be optioned to the minors, and it takes two days to get a player through waivers. So clubs will sometimes DFA a player when they need the player's slot on the 25-man roster, to give themselves time to secure Optional Assignment Waivers, and then once Optional Assignment Waivers have been secured, the player can be returned to the 40-man roster and get optioned to the minors. .
Barney has never been optioned to the minors, so he has all three minor league options left. Also, Barney cannot refuse an Optional Assignment until he has accrued five years of MLB Service Time, and he has accrued a few days less than four years of MLB Service Time to this point in time.
He can elect free-agency if he is outrighted to the minors (but not if he is optioned), but if he does get outrighted and then elects free-agency, he would forfeit what is left of his 2014 salary (but only if his contract is not guaranteed).

almora to TN seems a bit rushed, but at least it's enough time for him to be challenged at a new level rather than just getting a taste.

Soler has been playing like a
Soler has been playing like a man among boys across the board and needs to get on the fast track, so that promotion makes immediate sense. But I'm a little surprised by the Almora promotion. He's been hot lately, but his BB% remains frighteningly low and has been pretty much throughout his pro career.
Over is last 30 games (108
Over is last 30 games (108 ABs), Almora has a 380/404/611 line. Yes, only 5 walks, but also only 13 Ks. It just looks like he adjusted to the league and now needs a challeng.e
It will be interesting to see
It will be interesting to see if Almora's hitting changes out of the FSL which is notoriously tough on hitters. Also it will be interesting to see if he needs to make an adjustment to AA pitching. Relative to normal age for AA, how young is he for that league?

Mick Gillespie extended interview with Jorge Soler after getting recent player of the week award for the Smokies
So what are the dominoes here
So what are the dominoes here with Olt and Soler going to AAA and only Wada, a pitcher, coming up? I assume someone has to be released or demoted to AA?
The I-Cubs had 14 pitchers
The I-Cubs had 14 pitchers active (including Kyuji Fujikawa) prior to Wada getting called-up, so Olt would replace Wada on the Iowa Cubs Active List, and I would think Manny Ramirez will probably be placed on the 7-day DL with some kind of vague "soft tissue" injury to make room for Soler.
And then Szczur and Jackson will probably share CF, and Vitters and Kalish will probably share LF duties.
At Tennessee, Almora plays CF (obviously), so Jae-Hoon Ha would move to RF.
Billy McKinney can play CF (his natural position) at Daytona, with Schwarber in LF (when he isn't catching) and Bijan Rademacher in RF, although the Cubs could move Pin-Chieh Chen back down to Daytona from Tennessee to play CF for the D-Cubs (both John Andreoli and Rubi Silva are on the Tennessee 7-day DL and one or both could be reinstated at any time), or they might move Hannemann, Martin, or Dunston up to Daytona from Kane County to play CF.
Hannemann promoted to Daytona

Q-MAN: That makes a lot of sense. Why waste Lake's last minor league option with only six weks left in the minor league season?
Olt has two options left, so he'll still have one left next season even after using up one this season. But I still don't understand why he wasn't sent down earlier.
The Eloy Jimenez moonshot HR
The Eloy Jimenez moonshot HR last night for AZL Cubs at Cubs Park (Riverview Park) went over the LF berm and his walk-off RBI double hit off the right-centerfield wall.
2014 13th round draft pick Kevonte Mitchell (now playing CF) continues to impress... 6'4 "long-strider" with above-average speed, good baserunner, enough range to play CF, and a line-drive stroke with plus bat speed...
And AA RHP Ivan Pineyro (forearm strain) was throwing strikes with a 91-92 MPH fastball and an occasional change-up in his return to action (two innings). He looked very good for not having pitched in a game in more than two months.
Cubs top pitching prospect RHP C. J. Edwards (shoulder) is scheduled to get the start tonight for the AZL Cubs versus AZL Rangers at Surprise, so it looks like both Pineyro and Edwards are working their way back to Tennessee.

So I assume Olt will get most
So I assume Olt will get most of his ABs at first base? He obviously needs some reps. He may have one more brief window with the Cubs after the Cubs are finished with their summer cleaning frenzy. If he gets regular ABs at first, we're talking about some serious thunder in Iowa. Bryant, Baez, Olt, and Soler, and 4Aer Valaika smacks a few, as well.
I'd be tempted to have him do
I'd be tempted to have him do nothing but DH. I can barely manage one task at a time, so I'd recommend focusing on hitting to someone who is having trouble with hitting.
Apparently Olt had to tell
Apparently Olt had to tell the Cubs he needed to play every day in AAA, because they couldn't figure it out. Renteria's quotes are infuriating. I maintain he's a moran (sic):
I have some doubts about this
I have some doubts about this: "This story was not subject to the approval of Major League Baseball or its clubs."
Because yesterday, that same article quoted Renteria as saying he *couldn't* get Olt at bats because they weren't seeing enough left handed pitchers. That got struck out of the article later for some reason. I don't really understand how Renteria expected Olt to NOT have problems at the plate playing that sporadically. Even veterans don't hit as well when they don't play. That said, with the suddenly ridiculously high number of prospects the Cubs have in their system, Olt is going to need to light it up in Iowa if he wants to stick around.

This is from a Keith Law chat
This is from a Keith Law chat lasy week:
In you evaluation of Baez you mentioned makeup concerns with lapses in concentration and effort. Any chance that this is similar to the concerns that were expressed with Hanley Ramirez in the minors and he just bored with the minors?
Klaw (2:16 PM)
I've heard about coaches having trouble with Baez, and I've had scouts/execs from other teams saying he's got some questionable off-field relationships. But I'm much more concerned about a guy who has shown a habit of taking plays and at bats off from the moment he got into the minors, and even in a nationally televised game on Sunday still couldn't bother to make a routine throw properly.
(A few more Baez questions & comments)
Klaw (2:47 PM)
I've seen Baez every year since his senior year of high school - when he was always last out on the field to start each inning, and wore a different cap to stand out from his teammates - and there's always been something. An at bat mailed in. A play not made, or not made correctly. A groundball not run out. Baseball's a hard game for most players. Even Manny Ramirez was a ridiculous worker when it came to hitting. (Fielding, not so much.) You don't see or hear the same concerns on Bryant or Soler or Almora.
Has anyone heard anything like this from someone other than Law?
I was more concerned about
I was more concerned about the trouble with coaches and off-field relationships issues. Plus the taking plays off.
Not to rain on Law's
Not to rain on Law's evaluation of Baez but I'd like to hear input from Az Phil on his take on Law's comments.
It kind of doesn't matter
It kind of doesn't matter unless Baez becomes a star and a pain in the ass. Everything I've been reading lately though says he has a matured a lot. He looked like a player playing with a ton of intensity when I saw him in Round Rock, and he played second like he'd been playing at the MLB level for years, and playing it well. No matter what AZ said, it may have been a different Baez, people can change pretty quickly at that age under the right influence. You know that a kid is cocky when they put an MLB tattoo on the back of their neck before their first pro game. Big deal, he's got some swagger. This team could use it.

Just thinking about this AAA
Just thinking about this AAA team from last night and what a collection of current and former highly ranked prospects it was. I put the highest pre-season Baseball America prospect ranking for each by them and the year. All of these guys played in the game last night:

Jackson - #32 (2012)
Baez - #4 (2014)
Bryant - #8 (2014)

If Geoff Blum could be a Playoff hero, there is hope still...
Giants scare me. I think you're wrong about Bumgarner, he would pitch on short rest for Game 2 and then full rest for Game 5. Cueto would go Game 1, then short rest in game 4. Add in some really tough outs in that lineup and I want nothing to do with them. With that rotation they can easily steal a series.
Cards are a tough matchup. The rivalry evens out their comparable lack of talent. And like someone said, they love HRs, which is how to beat the Cubs. The upside is that I would feel really good about Lester twice against STL.

Soler likely to return Sunday, Maddon says
Right now, I'd like to see the Mets first, Giants 2nd.
I believe that since most of the team from last years' NLCS is on the squad this year, they will really amp their game up even more to kick their ass in payback for 2015.
The Giants just do not have the depth in years past, and I think all things equal - and at Wrigley - they could handle them.
I do not want to see the Cards, period. Or their fans, media, or Joe Buck.
I don't want to play Braves in the first round. Any friggin team in the league can win 3 of 5..I hate the first round. Furthermore, I wanted to play the Marlins in 2003 and the Mets over Dodgers last year.
With that said in reverse order:
3. Cardinals: It will be devastating to lose in the first round, but even worse to their main rival. It is increased incentive for the Cardinals, especially after last year. Cards would have nothing to lose, Cubs have everything to lose.
2. Giants: Rotation in the playoffs scare me a bit, but what a lousy team.
1. Mets--because of the losses in the rotation
2. Giants--because they're not the team they were BUT they maybe have bullshit even-year magic?
3. Cardinals--because rivalry and not making the playoffs hurts them more than losing in the NLDS plus getting eliminated by them in the playoffs would make for horrible sports commentary next throughout next season.
Who's asking?
CLE/DET rained out last night already, possible rain-outs in New York (vs. Baltimore), Boston(vs. Toronto) and Philly(vs. Mets) this weekend too.
Not only games involving playoff spots that would need to be played, but any that involve home field advantage.
I got the first one! Second one I'm not even sure what even/odd betting is.
any opponent preference for NLDS?
Mets are down to 1 great pitcher instead of 4. Syndegaard may pitch Sunday which means if Mets win the WC game, he'd be set up for Game 1. There's a chance they clinch a spot by Sunday so he'd pitch the WC and then we'd probably get Colon for Game 1. They've certainly had the hottest bats over the last week and month out of the WC options.

United States Patent PRODUCTION This invention relates to the production of catalysts or catalyst carriers in the form of hollow beads. More specifically, the invention relates to the production of catalysts by providing hollow beads with a catalytically active substance.
Finely divided catalysts in a fluidized bed are preferred for catalytic processes. These catalysts may be prepared by grinding solid catalytically active substances or by grinding solid inert substances which are used as carriers. In this method of preparation, a considerable fraction is wasted by the formation of extremely fine, dusty constituents. Moreover, the catalyst particles thus prepared are exposed to marked attrition and oWing to their irregular shape exhibit unsatisfactory fluidizing behavior. There has therefore been a change-over to imparting a spherical shape to such catalysts, for example by moving a sol through a water-insoluble medium, such as oil, under such conditions that the sol droplets are converted into spherical gel particles which are then allowed to solidify. This method is however confined to sols as initial materials. Spherical catalyst particles have also been obtained by spray-drying gels. While these beads are more resistant to attrition than ground solids, they are not durable enough owing to the brittleness, for example upon elastic shock, because marked internal stresses occur during drying of the beads.
We have now found that improved attrition resistance and service life and at the same time an improvement in the catalytic activity owing to an enlarged geometric surface of the beads are achieved by using catalysts or catalyst carriers in the form of hollow beads having cavities which are accessible from outside. Catalysts or catalyst carriers of this type are obtained by spraying a hydrogel containing at least 30% by weight of water, suspension and/or solution of a metal compound, advantageously after having been heated, at a pressure of 10 to 100 atmospheres advantageously in the presence of an expanding agent, through one or more nozzles into a tower shaped vessel, and at the same time introducing a gas heated to 300 to 700 C. in an amount of 4 to 18 cubic meters per kilogram of initial material in the neighborhood of at least one of the nozzles.
In the new process it is advantageous to correlate the pressure, the opening in each nozzle and the hourly throughput of the substance to be sprayed so that at least 80% of all the sieve fractions of the final beads have a diameter of more than 90 microns. If the characteristic of the beads is based on the grain size characteristics 8 and the uniformity coefficient it according to Pulfe, the value for these hollow beads lies between 5 =0.l3 at n=5 and 6 =0.35 at n=3 (see E. Puife, Zeitschrift fiir Erzbergbau und Metallhiittenwesen, volume 1 (1948), part 4, page 97 et seq.).
The catalytic activity of a catalyst particle is known 3,347,798. Patented Oct. 17, 1967 to depend on the size of the geometric surface. In the case of spherical particles, diffusion, which efiects exchange with the active places in the interior of the bead, proceeds too slowly. Sometimes, even in the case of carriers, it is not possible to utilize the whole inner surface. In the case of a hollow sphere, however, the geometric surface for the same radius is about twice as great as with the spherical shape. Diffusion into the interior of the sphere is facilitated and the whole surface thus becomes catalytically active. Moreover owing to the low inner stress of a hollow sphere, it has a longer service life, better mechanical resistance and advantages in sup ply and withdrawal of heat at the catalytically active centers of the particles. The hollow spheres are exposed to only slight mechanical abrasion and offer resistance to mechanical stresses, for example in a fluidized bed, even when brittle and hard materials are used, as in the case of silica gel. In the event of deposits of carbon and the like on the surface of the catalyst and mechanical stresses thereby set up, hollow spherical particles are also stable.
Suitable initial materials for the production of catalyst particles according to this invention are silicic acid hydrogels or alumina hydrogels, and also hydrogels of silicates and titanium dioxide, which are usually present in the form of a viscous mass having a solids concentration of between 15 and 40% by weight, particularly between 15 and 30% by weight.
For example silicic acid hydrogels obtained from waterglass are suitable. They are obtained by conventional methods by precipitating the gel from waterglass in suitable dilution, for example at a density of 1.15 to 1.25 g./ccm., at room temperature or slightly elevated tema mineral acid while mixing Well. A solution of one or more metal compounds, for example a solution of an aluminum, magnesium or zinc salt, may to the waterglass. Useful alumina hydrogels arle obtained by precipitation from solutions of aluminum sa ts.
Metal compounds, for example compounds of copper, silver, zinc, magnesium, aluminum, tin, lead, vanadium, chromium, molybdenum, tungsten, manganese, iron,
uid, such as alcohol or gasoline, or sprayed as an aqueous or alcoholic solution which becomes viscous by evaporatron or by the formation is then ground in a mill, for example a toothed disc mill or a corundum disc mill, until the mixture has becomefinely divided and mobile. It is however also possible to subject the solids to the grinding process without previous peptization. A uniform product is similarly obtained by prolonged and intense grinding. If necessary the solids content should be decreased to to 15% by weight by adding water. During grinding, sufficient heat is usually liberated to make additional heating of the initial material unnecessary. It is advantageous to add a portion of the ground material, for example 3 to 60% by weight, particularly 3 to 30% by weight, to the mixture prior to grinding. This will ensure that the grinding process is shorter and easier and the ground material more homogeneous. For the same purpose, 1 to particularly 2 to 8%, of the hollow spherical particles of catalyst or catalyst carrier may be added to the pasty mixture prior to grinding. The cavities of the beads are thus better formed. Peptization can be improved by supplying a part of the ground material before or during the addition of the peptizing agent.
In carrying out the process, the hydrogels, suspensions or solutions, advantageously in the most concentrated form possible and after having been heated to 30 to 90 C., are forced at a pressure of 10 to 100 atmospheres, particularly at about 20 to 85 atmospheres, through a nozzle having an opening of about 0.5 to 4 mm., particularly 1.2 to 3.5 mm. The nozzle is situated at the upper end of a vertical spray tower. If the spraying cone has an angle of 30, the gas inlet may be near the nozzle, and when the spray cone has a larger angle, for example 60, introduction of gas may be distributed over the entire cross-sectional area of the tower. The initial material and the gas pass cocurrent through the spray tower. The gas is heated up to about 300 to 700 C., particularly 350 to 650 C., and introduced into the spray tower in an amount of 4 to cubic meters, advantageously 5 to 10 cubic meters, per kg. of initial material.
The temperature and amount of gas in relation to the amount of initial material sprayed in per unit of time are particularly important for the construction of the hollow bead. An advantageous adjustment is a mean temperature drop of at least 50 C. per meter, for example 50 to 100 C. per meter from the gas inlet in the direction of flow to the middle of the tower. The droplets should form an extensible but already tough skin in the neighborhood of the nozzle. This process may be promoted by introducing cold air beside the nozzle. When the droplets pass into the hot gas current, the enclosed liquid should evap orate rapidly. The heat supplied must also be 'suflicient to effect evaporation of the bulk of the liquid present in the shell and/or decomposition of the metal compound. The thin surface layer of the droplets is stretched until finally a hollow head is formed by the droplet bursting at one point. Nitrates, oxalates, acetates and formates which decompose at the treatment temperature, or substances which contain water of crystallization and which give off their crystal water in the form of vapor at the treatment temperature are very suitable. It is advantageous however to add expanding agents, for example readily vaporizable or readily decomposable substances in an amount of 0.3 to 10% by weight, particularly 0.5 to 8% by weight, for example ammonia or ammonium salts, such as ammonium acetate, ammonium carbonate or ammonium nitrate, and also liquefied gases, such as ammonia or sulfur dioxide, low boiling amines, and also nitric acid, acetic acid and formic acid, their salts, or borax or boron phosphate.
The substances used for the peptization may also serve as expanding agents.
The drying period increases very rapidly with the size of the primary particles. In view of the high water contents of the materials used, very large drying towers would seen to be necessary for the production of particles having a diameter of more than 100 microns. Surprisingly, however, dryers of conventional design may be used. In general, drying towers having a height of 8 to 15 m., particularly 10 to 12 rn., and a diameter of about 3 m. are required for carrying out the process at an hourly throughput of about 300 to 600 kg, particularly 350 to 500 kg., or towers having a diameter of about 2 m. at an hourly throughput of about to about 280 kg., of initial material. Residence periods in the drying tower are about twenty to one hundred seconds.
Hollow beads prepared according to this invention, particularly those obtained from hydrogels, have particularly good catalytic properties if they show a maximum at about 10 and 10 A. in the pore distribution curve determined by the mercury method. The total volume of the macropores is usually between 0.05 and 0.3, particularly between 0.07 and 0.15 ccrn./ g.
Besides the possibility as described above of direct processing of metal compounds for example from suspensions according to this invention, there is also the possibility of heating hollow beads produced from bydrogels to temperatures of at least 400 C., particularly from 450 to 700 C. By this method, which is carried out as it Were in two stages, the hollow spherical carrier being prepared in the first stage and the catalytically active substance then applied to it, very active catalysts are obtained. This method also permits the production of a uniform carrier for several catalyses to which there are then applied the various catalytically active metallic components for the specific reaction.
In this embodiment of the process, a silicic acid hydrogel, alumina hydrogel or hydrogels of silicates and titanium oxide, which have a solids concentration of 15 to 40% by weight are used as initial materials. It is advantageous to use silicic acid hydrogels which have been obtained from watergla'ss. The acid may be introduced into the waterglass solution in order to set up the required acidity, for example a pH value of 2 to 5. The hydrogel then forms in the solution. It is however possible to add to the waterglass solution only such an amount of mineral acid that the hydrogel forms at a pH of more than 7. It is also possible to precipitate the hydrogel by means of a precipitant, for example ammonia or ammonium salts, from the waterglass solution which may if desired have been provided with acid. Mixtures of hydrogels formed in these various ways may also be used. The gels are treated with water, acidified water and/or ammoniacal Water at room temperature or slightly elevated temperature. A solution of one or more metal compounds, for example a solution of an aluminum, magnesium, zirconium or zinc salt, may also be added to the waterglass. Useful alumina hydrogels are obtained by precipitation from solutions of aluminum salts, aluminates, alcoholates or activated aluminum and water.
The procedure for the production of the hollow beads from the hydrogels has already been explained in detail above. The hollow beads are then heated to temperatures of at least 400 C., particularly at from 450 to 700 C., in a further treatment; a definite temperature may be maintained, or the material may be exposed to heat within a temperature range with a rising temperature, for example from 500 to 650 C., for a definite period. At the lower temperatures, half to two hours is usually required for the preheating. At temperatures of 550 to 650 C., treatment periods of only ten to thirty minutes are adequate. At even higher temperatures, the period may if desired be shortened further. The heating may be carried out in the presence of gases, for example air or nitro- After the heat treatment, the catalytically active substance is applied by impregnation or spraying on. It is preferably applied by impregnating the hollow beads with solutions of a metal compound. Aqueous or organic solutions, for example alcoholic solutions, may be used. All metal compounds which are normally applied to conventional carriers may be used as catalytically active substances, for example compounds of copper, silver, zinc, magnesium, aluminum, tin, lead, vanadium, chromium, molybdenum, tungsten, manganese, iron, nickel, cobalt,
platinum, palladium or mixtures of the same. Examples of suitable compounds are oxides, hydroxides, carbonates, nitrates, oxalates, acetates, formates, sulfides and also ammonium, phosphorus and boron complexes. It is advantageous to use mixtures of salts of easily volatile and difficulty volatile acids, for example a mixture of nitrates and salts of phosphoric acid.
Prior to, or after, impregnation with a solution of a metal compound, the hollow beads may also be provided with a halogen, such as fluorine, chlorine, bromine or iodine, a halogen hydracid or another halogen compound or acids, such as phosphoric acid, pyrophosphoric acid, nitric acid, acetic acid or oxalaic acid, in small amounts, for example 0.1 to 5% by Weight.
The catalyst is then dried and heated to 400 to 700 C. The hollow beads may also be mixed in the dry state with decomposable metal compounds, for example with a nitrate, an ammonium compound or an organic compound, and then heated to 400 to 700 C.
By reason of their hollow spherical construction, the catalysts and/or catalyst carriers have advantages, particularly in catalytic fluidized bed reactions, over the compact bead catalysts hitherto used. Application of the catalytically active substances, for example compounds of metals or phosphoric acid, is carried out by conventional methods, for example after pretreatment with halogen or halogen compounds. The catalysts may be used for carrying out a great variety of fluidized bed reactions at atmospheric or superatmospheric pressure, for example in the hydrogenation, oxidation, dehydrogenation, dehydration, polymerization, condensation, amination, reduction of aromatic nitro compounds, cracking, refining and reforming of hydrocarbons, alkylation of hydrocarbons or their derivatives, and also aromatic amino, nitro and aminonitro compounds by reduction or reaction with alcohols, and also the production of alkanolamines, diamines, diphenylamine and imines. Higher yields and/or more prolonged cycles between regenerations are achieved than with the prior art catalysts.
The invention is further illustrated by the following examples.
' Example 1 About 400 kg. of silicic acid hydrogel having a pH value of 8 and containing 83% of water, 0.1% of ammonia and 0.2% of Na O is introduced hourly into a container having a capacity of about 2 cu. m. At the same time and within the same period about 4 kg. of 65% nitric acid is sprayed onto the continuously added hydrogel. The material which is kept viscous by stirring is brought into a toothed disc mill and intensely ground therein with by weight of the ground material being returned. During grinding, the liquid mass heats up to about 80 C. The mass is sprayed by means of a high pressure pump at a pressure of 5 O atmospheres through a nozzle having a 1.8 mm. bore into the upper portion of a drying tower 11 m. in height and 3 m. in diameter. At the same time, 200 cu. m. (S.T.P.) per hour of unheated air is passed in around the nozzle and 5000 cu. m. (S.T.P.) of dry air which has been heated to 550 C. is passed in per hour through several points beside the nozzle. The spray cone has an angle of 30. A temperature of 190 C. is thus set up at the lower end of the drying tower. The temperature in the middle of the tower is about 30 C. above the outlet temperature, i.e. about 220 C. The end product contains 5.5% of adsorbed water. The grain size characteristic is 0.15 mm. and the uniformity coeflicient 3.2. of all sieve constituents are more than 90 microns. The dried material has well formed beads which exhibit at one or more points access to the cavities in the interior. If some of these beads are broken open it is found that the bulk of them are hollow beads in the form of shells.
If each 400 kg. of silicic acid hydrogel jelly has addedv to it about kg. of dried catalyst, the viscosity of the mass to be sprayed is increased somewhat and the hollow spherical shape forms better. When 20 kg. of already dried drying tower at a pressure 6 catalyst is added to each 400 kg. of original hydrogel, the powder density falls from 450 g./l. to about 360 g./l.
Example 2 An aluminum oxide hydrogel with of ammoniacal Water is peptized with 1% of acetic acid, with reference to the gel, while stirring. The mass is then ground in a corundum disc mill, a temperature of 40 C. thus being set up. The mass is further heated to C. As in Example 1, 500 kg. of the mass is sprayed under a pressure of 60 atmospheres through a nozzle having a 2.8 mm. bore into the upper end of a drying tower. 4000 cu. m. (S.T.P.) of air which has been heated to 580 C. is introduced into the tower through five openings near to the nozzle. There is a temperature gradient of 76 C./m. from the gas inlet to the middle of the tower. Hollow beads having about the same size as in Example 1 are obtained.
Example 3 An aluminum hydroxide gel having 80% of water is diluted with such an amount of ammonia water that the solids content of the mixture is 14%. The mass is ground in a corundum disc mill, a temperature of 40 C. being set up. Further processing is carried out as in Example 2 in a nozzle having a 2.5 mm. bore at an hourly throughput of 420 kg. and at a pressure of 50 atmospheres. The hollow beads have the following grain sizes:
have a diameter of more than Example 4 A solution of aluminum nitrate containing 4% of aluminum is mixed with the equivalent amount of a 50% solution of phosphoric acid. The solution is heated to 35 C. and sprayed into a drying tower. 3000 cu. m. (S.T.P.) of dry air at 600 C. is introduced at points distributed over the cross-section of the tower at the height of the nozzle cocurrently with 400 kg. of solution introspray cone forms an angle of 60. A temperature of 190 C. is set up in the middle of the tower. Hollow beads are 95% have a diameter of more than 90 microns and the following grain sizes:
5 =0.17 and 21:45.
Example 5 500 kg. of a jelly of silica gel containing 17% of solids (which and washing the product with ammonia water) is mixed with 500 kg. of a silica gel having 25% of solids (which has been precipitated from by adding sulphuric acid to value of less than 8 and washing the product with and 42 kg. of copper is added in the form of a 12% copper tetramine hydroxide solution. The Whole is ground in a corundum disc mill and injected at 60 C. through a nozzle having a 2.1 mm. bore into the above-mentioned of 55 atmospheres. With an hourly throughput of 400 kg. of this mixture, 3500 cu. m. (S.T.P.) of dry air which has been heated to 600 C. is introduced at the same time at several points near the nozzle. The temperature drops by 80 C. per 111. from the gas inlet to the middle of the tower. 99% of the hollow beads have a diameter of more than 90 microns. The grain sizes are: 6 =0.25 and n=5.
This catalyst is annealed at 400 C. and used for the hydrogenation of nitrobenzene at 28 to 290 C. At a throughput of 0.84 kg. of liquid initial material per hour,
Example 6 64 kg. of a cobalt acetate solution containing 5% of obtained of which" cobalt is mixed with 70 kg. of 25% ammonia water. Then kg. of powdered molybdic acid is stirred with 10 kg. of 25 ammonia water. The two batches are added together to 430 kg. of aluminum oxide hydrate paste containing of A1 0 The whole mixture is then stirred for two hours and 420 kg. per hour of the mixture is injected by means of a high pressure pump at a pressure of 50 atmospheres through a nozzle having a 2.5 mm. bore into the upper end of a drying tower having a height of 11 m. and a diameter of 3 m. At the same time 3000 cu. m. (S.T.P.) of dry air which has been heated to 500 C. is passed in at several points near the nozzle. The spray cone has an angle of 30. The grain size characteristic of the dried hollow bead-shaped particles is 6 :02 and the uniformity coetficient n:4. 97% by weight have a diameter of more than 100 microns. The material is heated to 480 C. The finished alumina catalyst contains 4% of cobalt oxide and 10% of molybdic acid.
Example 7 12 kg. of molybdic acid is suspended in 250 liters of distilled water. 12 kg. of ammonia water is slowly stirred in. A mixture of 2.1 kg. of 25% ammonia water and 1.8 kg. of 83% phosphoric acid and 21 kg. of ammonium vanadate is then added. The mixture is stirred intensely and evaporated until it has a pasty consistency. The content of dry substance is 58%. 240 kg./hour of the paste is sprayed into a drying tower having a height of 11 m. and a diameter of 1.9 m. through a nozzle having a 1.6 mm. bore at a pressure of atmospheres. At the same time 875 cu. m. (S.T.P.) of. dry air is passed in per kg. of paste near to the nozzle. The dry air has been preheated to 510 C. The temperature in the middle of the tower is 150 C. and the outlet temperature is 130 C. Grain sizes of the hollow spherical particles: 6 ==0.18 and 12:3.2. 90% of all the sieve constituents have a diameter of more than 90 microns.
Example 8 500 kg. of a silicic acid gel containing 17% of solids (which has been precipitated by stirring a waterglass solution into sulphuric acid at a pH less than 3 and the product washed with water) is mixed with 500 kg. of a silicic acid gel having 25% by weight of solids (which has been precipitated from the same initial components by introducing sulfuric acid into waterglass solution at pH less than 8 and washed with ammonia water). The mixture is ground in a corundum disc mill and injected at 60 C. through a nozzle having a 2.1 mm. bore into the above-mentioned drying tower at a pressure of 55 atmospheres. With an hourly throughput of 400 kg, 3500 cu. m. (S.T.P.) of dry air which has been heated to 600 C. is introduced at the same time at several points beside the nozzle. The temperature drops 'by 80 C. per meter from the gas inlet to the middle of the tower. 99% of the hollow beads obtained have a diameter of more than 90 microns. Grain size characteristic 5 :25; uniformity coefficient 11:5. The hollow beads are heated for one hour at 650 C. They are then impregnated with 42 kg. of copper in the form of a 12% copper tetramine hydroxide solution, dried at 200 C. and heated for one hour at 600 C. A vertical cylindrical reactor having a ratio of diameter to height of 1:4 is filled to foupfifths of its free space with the catalyst. A grate is provided at the bottom of the vessel to ensure uniform distribution of the circulating gas supplied at the bottom. A cyclone is situated in the upper portion of the vessel which is widened to 1 /2 times, and entrained catalyst dust is separated in the cyclone. The vessel has twenty two-component nozzles arranged at different levels. The first group of eight nozzles is situated about one tenth of the height above the grate, the second group of seven nozzles is about one quarter of the height above the grate and the uppermost group of five nozzles is about one-third of the height above the grate. Air is first expelled from the reactor by introducing nitrogen, and then the catalyst is reduced with hydrogen at a temperature between 200 and 250 C. After the catalyst has been reduced, an operating pressure of 5 atmospheres is set up in the reactor and liquid nitrobenzene is sprayed into the reactor in finely divided form through the two-component nozzle by means of hydrogen. 65 kg. of nitrobenzene and 55 cu. m. (STAR) of hydrogen are supplied per hour in uniform distribution through the twenty two-component nozzles by means of pumps. A pressure of 6 atmospheres is maintained in the reactor. The reaction gases leave the reactor through the cyclone and pass by way of a heat exchanger and condenser to a separator in which the aniline formed and the water are separated from the gas. The gas is returned to the process through a preheater by means of a circulating pump. 325 cu. m. (S.T.P.) of recycle gas is passed per hour upwards through the distributor grate, the hydrogen content being kept constant by adding 375 cu. m. (S.T.P.) per hour of fresh hydrogen.
In the rigidly arranged catalyst layer of the reactor, a sufficient number of tubes is arranged at a distance of 25 cm. form and parallel to the wall of the reactor to provide a cooling surface which will maintain a temperature of about 280 C. 49.15 kg. of aniline and 19 kg. of water are obtained per hour in the separator. The aniline is obtained by simple distillation in a purity of almost 100% and a content of nitrobenzene of less than 0.01% with a yield of 99.5% of the theory with reference to the nitrobenzene introduced. After a throughput of 270,000 kg. of nitrobenzene per cu. m. of catalyst filling, a slight amount of a residue occurs on the catalyst. The full activity of the catalyst may be restored by regenerating it with air at 350 C. and then reducing it again in the way described above.
