ABSTRACT:
A fluidized catalytic cracking process for conversion of hydrocarbon charge to cracked products wherein a regenerated fluidized catalytic cracking catalyst having deposited thereon about 1000 to 10,000 ppm of nickel, vanadium, iron or mixtures thereof is treated with a sodium compound prior to use for cracking hydrocarbon charge such that hydrogen yield is increased.
