ABSTRACT:
A process is disclosed for treating a sour hydrocarbon stream comprising extracting the mercaptans contained in said hydrocarbon stream with an alkaline solution in an extraction zone, oxidizing the mercaptans to disulfides in the presence of an oxidation catalyst, separating said disulfide from said alkaline solution, reducing the residual disulfides in said alkaline solution to mercaptans and recycling said alkaline solution to the extraction zone. Two ways are disclosed to effect the reduction of the disulfides to mercaptans: (1) hydrogenation with a supported metal catalyst and (2) electrochemical reduction.
