How do zeolites catalyse the cracking of hydrocarbons?
The video you reference to does not tell the whole story.  Yes, zeolites are minerals with open pores, similar to a filter, occurring in nature and are produced commercially, too. Equally to their structure, their composition is interesting -- as both are used to tailor the reactivity and selectivity of this material.  ZSM-5 is one example of designed remarkably high Brønsted acidity.  Hydrocarbons in contact with these sites split into fragments and rearrange because of the intermediate generation of carbocations.  It is advantageous, as these reactions are heterogeneously catalysed by these "solid state acids".
