The reactions taking place in zeolites depend on-
They are good shape selective catalysts due to their honey-comb like structures
They are three dimensional network of silicates where some silicon atoms are replaced by aluminium atoms forming a Al-O-Si network.
Zeolites are microporousaluminosilicates.
The catalytic reaction which depends upon the pore structure of the catalyst and the size of the reactant and product molecules is called shape-selective catalysis
The size and shape of the reactants and product molecules
The pores and cavities of the zeolites
Widely used as catalysts in the petrochemical industry for cracking of hydrocarbons and isomerisation
Eg: ZSM-5 is used in converting alcohols directly to gasoline(petrol) by dehydrating them
