Abstract
The process for the desulfurization of a sulfur-containing hydrocarbon mixture, such as a full-range, hydrotreated diesel oil, is accomplished with an aqueous oxidizing agent in the presence of a catalyst and a co-catalyst, and thereafter selectively removing the oxidized compounds by solvent extraction. Optionally, the foregoing steps are followed by solvent stripping and recovery, and a final polishing step.
