Abstract
A catalytic mixture of discrete solid materials and a mercaptan oxidation process for using the catalytic mixture have been developed. The catalytic mixture comprises a 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 with the supported metal chelate and the solid base mixture in the presence of an oxidizing agent and a polar compound. The process is unique in that both the catalyst and the base are discrete solid materials.
