While these anti-fatigue mats can be effective at improving worker morale and productivity, they make it difficult to clean the floor such as sweeping and vacuuming, as well as creating tripping hazards. Accordingly, there is a need in the art for an improved anti-fatigue flooring system which provides the increased comfort, safety and productivity provided by the mats but without the inconveniences of the mats. Propene (C3H6), often also referred to as propylene, is one of the most important starting substances of the chemical industry. The demand for the base material propylene is increasing worldwide, wherein propylene just like ethylene mostly is produced from petroleum in a steam cracker in a ratio dependent on the process and the raw materials.
To obtain additional propylene, a number of processes exist, such as the PDH process which proceeds from propane as educt. What is known, however, above all is the so-called MTP process, in which olefins are produced from methanol (MeOH) or dimethyl ether (DME) by catalytic conversion on a zeolitic catalyst. By varying the catalyst under process conditions, the selectivity of the products obtained can be influenced and the product spectrum thus can be shifted towards short-chain olefins (then often also the process name Methanol-to-Olefin (MTO)), towards longer-chain products (then often also the process name Methanol-to-Gasoline (MTG)) or towards propylene.
The fundamentals of an MTP process are described for example in DE 10 2005 048 931 A1. From an educt mixture containing steam and oxygenates, such as methanol and/or dimethyl ether, C2 to C4  olefins are produced above all. By a heterogeneously catalyzed reaction in at least one reactor, the educt mixture is converted to a reaction mixture comprising low-molecular olefins and gasoline hydrocarbons. By a suitable separation concept, higher olefins, above all the C5+ fraction, can at least partly be recirculated into the reactor as recycling stream and in said reactor for the most part be converted to propylene, whereby the propylene yield is increased.
One problem when carrying out the MTP process consists in that very pure oxygenates must be used as starting substances. When e.g. methanol is used as educt of the MTP reaction, this methanol must have a degree of purity of the specification

 While these anti - fatigue mats can be effective at improving proletarian esprit de corps and productivity, they make it unmanageable to clean the floor such as sweeping and vacuuming, equally well as creating tripping hazards. consequently, there is a need in the art for an improved anti - fatigue floor arrangement which provides the increase comfort, safety and productiveness provided by the mats but without the inconveniences of the mats. Propene (C3H6), often also referred to as propylene, is one of the about important starting substances of the chemical diligence. The demand for the base material propylene is increasing worldwide, wherein propylene just like ethylene largely is produced from petroleum in a steam cracker in a ratio dependent on the process and the naked materials. 
 To obtain additional propylene, a number of processes exist, such as the PDH procedure which proceeds from propane as educt. What is known, however, above all is the so - called MTP process, in which olefins are produced from methanol (MeOH) or dimethyl ether (DME) by catalytic conversion on a zeolitic catalyst. By varying the catalyst under process conditions, the selectivity of the merchandise obtained can be influenced and the intersection spectrum therefore can be careen towards short - chain alkene (then often besides the process name Methanol - to - Olefin (MTO) ), towards longer - chain intersection (then often also the process name Methanol - to - Gasoline (MTG) ) or towards propylene. 
 The fundamentals of an MTP process are report for example in DE 10 2005 048 931 A1. From an educt mixture containing steam and oxygenates, such as methanol and/or dimethyl ether, C2 to C4   olefins are grow above all. By a heterogeneously catalyzed reaction in at least one nuclear reactor, the educt mix is converted to a reaction mixture comprising gloomy - molecular olefins and gasoline hydrocarbons. By a suitable separation concept, higher olefins, above all the C5 + fraction, can at least partly be recirculated into the reactor as recycle stream and in say reactor for the most region be converted to propylene, whereby the propylene output is increased. 
 One trouble when carrying out the MTP process consist in that very pure oxygenates must be used as begin substances. When for example methanol is used as educt of the MTP reaction, this methanol must have a academic degree of purity of the specification
