Shape Selective Catalysis By Zeolites |
|
Answer» The catalystic reaction which depends upon the pore size of the catalyst and the size of the reactant and product molecules is called shape-selective catalysis. Zeolites are good shape-selective catalysts because of their honey comb like structures. ZSM-5 is used in petroeum industry to convert alcohols directly into gasoline by dehydrating them to give a mixture of hydrocarbons. `xCH_(3)-Ooverset(ZSM-5)(rarr)underset("Gasoline")((CH_(2))_(x))+xH_(2)O` The catalystic reaction which depends upon the pore size of the catalyst and the size of the reactant and product molecules is called shape-selective catalysis.
