In a process which comprises the cracking, in the absence of added hydrogen, of a metals-containing hydrocarbon 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 alumina to form a catalyst composite containing a weight ratio of said high activity cracking catalyst to alumina in the range of 50:50 to 90:10, said diluent forming a separate and distinct entity within said catalyst composite.
