ABSTRACT:
A catalytic cracking process is provided in which a zeolitic cracking catalyst having the structure of faujasite is first regenerated, then coked at a high catalyst to hydrocarbon weight ratio, and, subsequently utilized to crack a hydrocarbon feed boiling from about 430.degree.F. to 1050.degree. F. at a lower catalyst to hydrocarbon feed ratio.
