-88- ABSTRACT OF THE DISCLOSURE This application discloses novel fluid catalytic cracking catalysts comprising microspheres containing more than about 40%, preferably 50-70%, by weight Y-faujasite zeolite, methods for making such catalysts, and the use of such catalysts to crack petroleum feedstocks, particularly those con- taining large amounts of contaminant metals. The microspheres of the catalyst of the invention are characterized by a combination of desirable catalyt- ic and physical characteristics, including excep- tionally high activity, excellent hydrothermal stability, good to excellent attrition resistance, and desirable selectivity characteristics.
