ABSTRACT:
A catalytic system of physically separate and discrete solid materials and a mercaptan oxidation process for using the catalytic system have been developed. The catalytic system comprises a supported metal chelate dispersed on a non-basic solid support and a solid base. The process involves contacting a sour middle distillate hydrocarbon fraction which contains mercaptans first with the solid base and then, in the presence of an oxidizing agent and a polar compound, with the supported metal chelate. The process is unique in that both the catalyst and the base are solid materials and that the solid base is in a separate fixed bed from the supported metal chelate.
