The advantages of catalytic cracking over thermal cracking are as follows
- Catalytic cracking takes place at lower temperature and pressure (3000C -4000C and 1-5kg/cm2 ) as compared to that of thermal cracking (5000C-6000C and kg/cm2)
- Catalytic cracking yields a higher quantity of branched-chain, unsaturated, aromatic hydrocarbons as compared to thermal cracking.
- Catalytic cracking is a better-controlled process than thermal cracking.
- Petrol obtained by catalytic cracking has lesser sulfur content.
