Advantages of catalytic cracking over thermal cracking

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.
