OCTANE IMPROVEMENT CRACKING CATALYST

摘要

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 comprising 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.
