Question

Name the shape selective catalyst used in the petroleum industry

Answer 1

Zeolites as shape selective Catalysts:- zeolites are aluminosilicates with the general formula Mx/n [(AlO2)x(SiO2)y]. ZH2O when n is charge on metal cation Mn+. Which is usually Na+, K+, Ca+. they are microporous three dimensional network silicates in which some silicon atoms are replaced by aluminium atoms. Giving Al-O-Si frame work.

Zeolites are being very widely used as catalyst in petrochemical industries for craking of hydrocarbons and isomerization an important zeolite catalyst used in petroleum industry is ZSM – 5•••. It converts alchol directly into gasoline.
