Abstract
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 containing large amounts of contaminant metals. The microspheres of the catalyst of the invention are characterized by a combination of desirable catalytic and physical characteristics, including exceptionally high activity, excellent hydrothermal stability, good to excellent attrition resistance, and desirable selectivity characteristics.
