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 so as to form a mix thereof;(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 cobalt or a cobalt-containing compound;(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 wherein the valence of essentially all of the cobalt therein is zero such that the reduced cobalt-containing composition will affect the removal of sulfur from a stream of cracked-gasoline or diesel fuel when said stream is contacted with said reduced cobalt-containing composition.
