THERMAL CONVERSION PROCESSES
Thermal cracking was the first process used to increase gasoline production. After the development of catalytic cracking, which improved yields and product quality, thermal cracking was given other roles in refinery operations. The three important thermal cracking techniques are coking, viscosity breaking, and steam cracking. Steam cracking is of special importance as a major process designed specifically for producing light olefins.
