ABSTRACT:
Octane and total yield improvement in catalytic cracking of petroleum fractions under cracking conditions can be obtained by adding to conventional cracking catalysts small amounts of an additive catalyst comprising a class of zeolites characterized by a silica to alumina mole ratio greater than 12 and a constraint index of 1 to 12 wherein the zeolite additive catalyst has a crystal size of between 0.2 to 10 microns.
