ABSTRACT:
A process for increasing gasoline octane number and/or total gasoline yield in catalytic cracking units by the addition of a very small amount of finely divided shape selective additive promoter, which additive promoter is not intimately combined with a substantial amount of another solid prior to contact with the cracking catalyst. The additive promoter is a zeolite characterized by a silica to alumina mole ratio greater than about 500 and a constraint index within the approximate range of 1 to 12.
