Catalysts capable of desulfurizing organo-sulfur compounds particularly those normally found in petroleum compositions, such as thiophene, are prepared from metal-containing compounds of metals of Groups VIB and VIII of the Periodic Table on a refractory support or base. Of particular interest are catalysts containing components of cobalt and molybdenum oxides on alumina which preparation utilizes dimethyl sulfoxide (DMSO). The use of such catalysts provides increase of conversion rate-constants of desulfurization reactions. A process of treating the base and the base material obtained from such process are also disclosed herein. |
