Attrition resistant, sorbent compositions for the removal of elemental sulfur and sulfur compounds, such as hydrogen sulfide and organic sulfides, from cracked-gasoline and diesel fuels are prepared by the impregnation of a sorbent support comprising zinc oxide, expanded perlite, and alumina with a promoter such as nickel, nickel oxide or a precursor of nickel oxide followed by reduction of the valence of the promoter metal in the resulting promoter metal sorbent support composition.

1. A calcined and reduced sorbent composition suitable for removal of elemental sulfur and sulfur compounds from cracked-gasoline and diesel fuels which prior to calcining and reduction is comprised of:(a) zinc oxide; (b) expanded perlite; (c) alumina; and (d) a promoter metal wherein said promoter metal is present in an amount which will effect the removal of sulfur or sulfur compounds from a stream of cracked-gasoline or diesel fuel when contacted with same under desulfurization conditions and at least a portion of said promoter metal is present in a zero valence state.
