Abstract
In a catalytic cracking process for heavy oil which comprises contacting a heavy oil with a particulate mixture of a crystalline aluminosilicate-containing cracking catalyst particle and an alumina particle and/or a phosphorus-containing alumina particle mixed in the weight ratio of 80/20-20/80, under cracking conditions, metal contaminants contained in said feed oil are captured preferentially by said alumina particle and/or a phosporous-containing alumina particle, and the coexistent cracking catalyst is poisoned only to a reduced degree by metal contaminants.
