[57] Abstract: The present invention concerns a novel additive composition for reducing sulfur content of a catalytically cracked gasoline fraction. This additive composition comprises a support consisting of porous clay into which a first metal from group IV is incorporated and a second metal from group II is impregnated. Preferably, the first incorporated metal is zirconium and the second impregnated metal is zinc. The sulfur reduction additive is used in the form of a separate particle in combination with a conventional fluidized catalytic cracking catalyst in a fluid catalytic cracking process to convert hydrocarbon feed stocks into gasoline and other liquid products.
