Fluid catalytic cracking process for increased formation of isobutylene and isoamylenes |
| 摘要 |
A composite fluid catalytic cracking catalyst comprising a non-zeolitic component of at least 45% Al2O3 and containing </=30% Y zeolite with unit cell size </=24.29 ANGSTROM , the matrix (non-zeolitic component) of said catalyst having a B.E.T. surface area >/=50 m2/g and a catalyst Lewis/Bronsted acid site ratio of >/=1.5 wherein the total number of Bronsted acid sites is </=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.
