ABSTRACT:
Octane and total yield improvement in catalytic cracking processes can be attained by the addition to conventional cracking catalysts of very small amounts of additive catalyst comprising a class of zeolites characterized by a silica to alumina mole ratio greater than about 12 and a constraint index of about 1 to 12. The additive catalyst is added to the conventional cracking catalyst in the cracking process in an amount which provides the zeolite component of the additive catalyst at from about 0.01 weight percent to about 1.0 weight percent of the conventional cracking catalyst in the cracking process.
