  • Patent number: 5286369
    Abstract: Catalyst compositions are described which comprise crystalline molecular sieve zeolites and an aluminum phosphate component having a surface area of less than about 50 m.sup.2 /g and a high degree of attrition resistance. The catalysts are particularly effective for the catalytic cracking of high molecular hydrocarbon feedstocks to obtain enhanced yields of C.sub.3 and C.sub.4 olefins such as isobutylene.
    Type: Grant
    Filed: October 26, 1992
    Date of Patent: February 15, 1994
    Assignee: W. R. Grace & Co.-Conn.
