摘要：Catalyst compositions are described which comprise crystalline molecular sievezeolites and an aluminum phosphate component having a surface area of less than about50 m²/g and a high degree of attrition resistance. The catalysts are particularly effectivefor the catalytic cracking of high molecular hydrocarbon feedstocks to obtain enhanced
yields of C₃ and C₄ olefins such as isobutylene.
