A process for the production of a sorbent composition suitable for the removal of sulfur from cracked gasoline or diesel fuel, comprising: (a) mixing zinc oxide, silica and alumina to form a mixture thereof in the form of a wet mixture, mass , paste or suspension; (b) particular the resulting mixture to form particulate material thereof in the form of one of granules, extrudates, tablets, pills, spheres or microspheres; (c) drying the resulting particulate material; (d) calcining the dried particulate material; (e) impregnating the calcined particulate material with a bimetallic promoter formed by any two metals selected from nickel, cobalt, iron, manganese, copper, zinc, molybdenum, tungsten, silver, tin, antimony or vanadium; (f) drying the impregnated particulate material from step (e); (g) calcining the dried particulate material from step (f); and thereafter (h) reducing the calcined particulate material resulting from step (g) with hydrogen to produce the sorbent composition, in which the bimetallic promoter is present in a reduced valence state and the weight ratio of the metals of said bimetallic promoter is in the range of 20: 1 to 1:20. |
