US 2013/0210613 A1 · CATALYST ADDITIVE FOR REDUCTION OF SULFUR IN CATALYTICALLY CRACKED GASOLINE

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 IVB is incorporated and a second metal from group IIB 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 cracking catalyst in a fluidized catalytic cracking process to convert hydrocarbon feed stocks into gasoline having comparatively lower sulfur content and other liquid products.

Dependent claims

A fluid catalytic cracking (FCC) mixture comprising an FCC catalyst and separate particles of sulfur reduction additive, in which the particles of sulfur reduction additive comprise:

a porous montmorillonite clay support, having a zirconium component and a Lewis acid compound from Group IIB of the Periodic Table wherein the zirconium component is first incorporated into the pore structure of the support material to thereby increase the surface area of the support material and the Lewis acid compound is subsequently impregnated on the surface of the support material.
