Abstract
Catalytic cracking catalysts and their use in catalytic cracking processes are disclosed. The instant catalytic cracking catalysts are useful for cracking a hydrocarbon feedstock to produce lower boiling hydrocarbons. The catalysts comprise an effective amount of at least one non-zeolitic molecular sieve characterized in its calcined form by an adsorption of isobutane of at least 2 percent by weight at a partial pressure of 500 torr and a temperature of 20.degree. C. The non-zeolitic molecular sieve is characterized as containing framework tetrahedral components of aluminum and phosphorus and at least one additional framework tetrahedral component, e.g., the non-zeolitic molecular sieve may be a silicoaluminophosphate as described in U.S. Pat. No. 4,440,871.
