Abstract
A cracking catalyst comprising discrete particles of ultra-stable Y-type zeolite and discrete particles of alumina, which particles are dispersed in a porous oxide matrix to produce a catalyst containing 5-40 wt. % ultra-stable Y-type zeolite, 5-40 wt. % alumina and 40-90 wt. % of porous oxide matrix. The cracking catalyst has unusually high activity and selectivity for the production of high octane gasoline fractions from higher boiling point feedstocks.
