Abstract
Lakehead University, Thunder Bay P, Ontario, studied the activity of cobalt molybdate and related catalysts in the oxidation of hydrogen sulfide at concentrations below 400 ppM and found them to be highly efficient in oxidizing H/sub 2/S to SO/sub 2/. Cobalt molybdate and mixtures of cobalt and molybdenum oxides supported on ..cap alpha..-alumina were the most effective catalysts and at 482/sup 0/F (250/sup 0/C) allowed the reduction of hydrogen sulfide to levels below its odor threshold (0.007 ppM) provided that the initial concentration of H/sub 2/S did not exceed 1000 ppM. The effects of oxygen concentrations up to 4.3% and water-vapor concentrations up to 12% are described along with the effect of sulfiding on catalyst activity and a possible method for regeneration.
