    • 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.

    • A system is described for control of sulfur oxide in emissions to the atmosphere from the combined flue gases of selective vaporization and FCC cracking of the improved charge stock resulting from selective vaporization. The invention provides for reduction in sulfur oxide content of the waste gases from the FCC regenerator and the selective vaporization burner and adds a new controllable variable for a heat balanced FCC Unit. The cracking catalyst used has the capability of reversibly reacting with sulfur oxides in the combined flue gases to carry the sulfur back into the reactor where it is converted, at least in part, to hydrogen sulfide which is removed from reaction products in the normal course of treating the cracked products from the reactor. By the disclosed system, the blend of flue gas is cooled and then contacted with hot regenerated catalyst from the regenerator for sorption of sulfur oxides by the catalyst and to cool the catalyst for control of reaction parameters in the FCC reactor.

    • Whole crude and residual fractions from distillation of petroleum and like feed stocks are subjected to selective vaporization to prepare heavy fractions of reduced Conradson Carbon and/or metals content by short-term, high temperature riser contact with a substantially inert solid contact material of low surface area in a selective vaporization zone. High boiling point components of the charge which are of high Conradson Carbon number and/or high metal content remain on the contact material as a combustible deposit which is then burned off in a combustion zone whereby the contact material is heated to a high temperature for return to the selective vaporization zone to supply the heat required therein. Equilibrium FCC catalyst, previously treated to reduce catalytic cracking activity and surface area, is used as the substantially inert solid.
