Abstract:
A process for the production of a sorbent composition suitable for the removal of sulfur from a cracked-gasoline or diesel fuel stream which comprises:(a) admixing of zinc oxide, silica and alumina and a calcium compound selected from the group consisting of calcium sulfate, calcium aluminate, calcium phosphate and calcium silicate;(b) particulating the resulting mix so as to form particles thereof;(c) drying the particulate of step (b);(d) calcining the dried particulate of step (c);(e) impregnating the resulting calcined particulate of step (d) with a metal, metal oxide or metal oxide precursor promotor wherein the metal is selected from the group consisting of cobalt, nickel, iron, manganese, copper, molybdenum, tungsten, silver, tin and vanadium or mixtures thereof;(f) drying the impregnated particulate of step (e);(g) calcining the dried particulate of step (f); and thereafter(h) reducing the resulting calcined particulate of step (g) with a suitable reducing agent under suitable conditions to produce a particulate composition having a substantial reduced valence promotor metal content therein such that the reduced valence promotor metal containing composition will effect the removal of sulfur from a stream of cracked-gasoline or diesel fuel when said stream is contacted with said reduced valence promotor metal containing composition under desulfurization conditions.
