Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A fluid catalytic cracking (FCC) mixture consisting of (i) an FCC catalyst and (ii) separate particles of sulfur reduction additive, said particles of sulfur reduction additive consisting of: a clay support consisting of porous montmorillonite clay; a zirconium component; and zinc, wherein the zirconium component is incorporated into the pore structure of the porous montmorillonite clay support to thereby increase surface area of said clay support and the zinc is impregnated on the surface of the porous montmorillonite clay support. 2. The mixture according to claim 1 , wherein the sulfur reduction additive contains from about 1 to about 5 weight percent of zirconium based on the total weight of the additive. 3. The mixture according to claim 1 , wherein the sulfur reduction additive contains from about 1 to about 10 weight percent of zinc based on the total weight of the additive. 4. The mixture according to claim 1 , wherein the concentration of the sulfur reduction additive is from about 10 to about 20 weight percent of the cracking catalyst.
