Discuss some features of catalysis by zeolites.

Explanation

`to` The catalytic reaction that depends upon the pore structure of the catalyst and the size of the reactant and product molecules is called shape selective catalysts.
`to` Zeolites are shope selective catalysts because of their honey comb-like structure. They are microporous alumino silicates with 3-dimensional net work of silicates.
`to` Zeolites are microporous alumino silicates with dimensional network of silicates in which some Si-atoms are replaced by aluminium atoms giving Al -O-Si frame work
`to` The reactions taking place in zeolites depend upon the size and shape of reactant and product molecules as well as on the pores and cavities of the zeolites.
`to` Zeolites are found in nature and also synthesized for catalytic selectivity.
Uses :
`to` Zeolities are used as catalysts in petrochemical industries for cracking.
`to` Zeolite ZSM -5 is used to covert alcohol directly into gasoline (petrol) by dehydrating them to give a mixture of hydrocarbons.
