摘要：
The invention relates to improving the selectivity of the production of isobutylene or 2-methylpropene during fluid catalytic cracking of heavy C.sub.9 + aromatic containing feeds including resids and/or gas oils by employing two catalyst components, one of which comprises ZSM-23, ZSM-22, ZSM-35 or similarly structured catalysts and the other catalyst component being effective under the fluid catalytic cracking conditions to produce high octane gasoline.
