In a process which comprises the cracking, in the absence of added hydrogen, of a vanadium-containing hydrogen feed in a cracking zone under cracking conditions employing a cracking catalyst having high activity; the improvement which comprises combining with said catalyst a diluent consisting essentially of magnesium oxide to form a catalyst composite, said diluent forming a separate and distinct entity within said catalyst composite, and the concentration of said diluent within said composite being adjusted so as to be directly proportional to the concentration of vanadium on said catalyst composite in said cracking zone and wherein said concentration of said diluent is in the range of 20-50 weight percent of said catalyst composite.
