ABSTRACT:
A composite fluid catalytic cracking catalyst comprising a non-zeolitic component of at least 45% Al.sub.2 O.sub.3 and containing .ltoreq.30% Y zeolite with unit cell size .ltoreq.24.29 .ANG., the matrix (non-zeolitic component) of said catalyst having a B.E.T. surface area .gtoreq.50 m.sup.2 /g and a catalyst Lewis/Bronsted acid site ratio of .gtoreq.1.5 wherein the total number of Bronsted acid sites is .ltoreq.30 micromoles/g of catalyst. The catalyst is used to increase the isobutylene and isoamylenes content of cracked products obtained in a fluid catalytic cracking unit.
