摘要：A cracking catalyst comprising discrete particles of ultra- stable Y- type zeoliteand discrete particles of alumina, which particles are dispersed in a porous oxide matrix toproduce a catalyst containing 5- 40 wt. % ultra-stable Y-type zeolite, 5-40 wt. % aluminaand 40-90 wt. % of porous oxide matrix. The cracking catalyst has unusually high activityand selectivity for the production of high octane gasoline fractions from higher boilingpoint feedstocks.
