Octane and total yield improvement in catalytic cracking

Patent ·
OSTI ID:5753123
; ;
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 12 and a constraint index of about 1 to 12. The weight ratio of said zeolite of the additive catalyst to the amount of active component, e.g. faujasite zeolite, in the conventional cracking catalyst ranges from between about 1:400 and about 1:15.
