FIELD: petroleum processing and petrochemical processes.
SUBSTANCE: invention relates to some catalyst compositions and processes capable of lowering level of sulfur compounds commonly present as parts of gasoline fraction streams in fluidized-bed catalytic cracking processes. Equilibrium cracking catalyst composition is used comprising at least one Y-type zeolite having kinetic activity in feedstock conversion equal to about 3 combined with alumina-based composite, which contains Lewis acid in amount of at least 50% by weight based on the total catalyst composition.
EFFECT: achieved kinetic activity of equilibrium catalyst during feedstock conversion equal to about 2.
