Question

Zeolites are used as catalyst in

• A. Petrochemical industries during cracking
• B. production gasoline from alcohol
• C. In the preparation of $H_{2}S{O}_4$
• D. In the hydrolysis of ester

Answer 1

Answer: (A), (B)

production gasoline from alcohol

Zeolite is a microporous aluminosilicates ​with 3D network of silicates ​in which some silicon ​atoms are replaced by​ Aluminium atoms giving ​Al-O-Si framework. ​

The pore size of zeolites​ is $260-270pm$
General formula of zeolite is​ $N{a}_{x/n}\left[\right(Al{O}_2{)}_x\left(Si{O}_2{)}_y\right].z{H}_{2}O$

Zeolites are good shape-selective catalysts because of their honeycomb-like structures.​

Uses of Zeolite:
1. Used as a catalyst in petroleum industries for cracking of hydrocarbon and isomerisations​.
2. Can convert alcohol directly into gasoline by dehydrating them to ​give a mixture of hydrocarbon.​
