Abstract: There is provided a method for improving the attrition resistance and heat stability of a silica-alumina fluid catalytic cracking catalyst where the catalyst contains up to 35 weight percent alumina by treating the catalyst with steam such that the catalysts stability factor is increased to a value of at least 12.5. The above treatment provides an improved fluid catalytic cracking catalyst for utilization for the cracking of a hydrocarbon charge under the catalytic cracking conditions.

Abstract: There is provided a method for increasing the catalytic cracking activity, selectivity and attrition resistance of a crystalline aluminosilicate containing catalytic cracking catalyst by treating the catalyst at a temperature above about 1300*F. and below the thermal destructive temperature of the crystalline aluminosilicate in the absence of steam. The above treatment provides an improved catalytic cracking catalyst for utilization in the cracking of a hydrocarbon charge under catalytic cracking conditions.
