Abstract

Compositions which contain a titania component have been found which provide reduction of sulfar levels in the gasoline resulting from FCC processes (and other cracking processes conducted in the absence of added hydrogen) without the need for feedstock pretreatments nor added hydrogen. The compositions preferably also contain an alumina supported Lewis acid component. These compositions are preferably used as particles in admixture with catalytic cracking catalyst particles in the circulating catalyst inventory.
