Abstract
The present invention is directed to a fluid catalytic cracking catalyst comprising a blend of a catalytically active first component and a second component for reducing the emissions of oxides of sulfur from the regenerator of a catalytic cracking unit and the use of that catalyst to crack sulfur containing petroleum feedstocks. The catalytically active first component contains Y-faujasite zeolite and comprises about 10-70% by weight, preferably about 25-50% by weight, of the catalyst. The second component of the catalyst comprises about 30-90% by weight, preferably about 50-75% by weight, of the catalyst. The second component comprises fluidizable particles containing at least about 70% by weight, preferably at least about 90% by weight, alumina and having an equilibrium surface area in the range of about 40-100 m.sup.2 /g., preferably in the range of about 50-90 m.sup.2 /g.
