    摘要: The electrodesulfurization of heavy oil feedstreams is accomplished wherein a heavy oil feedstreams, along with hydrogen, is passed the cathode side of an electrochemical cell wherein the organically bound sulfur compounds in the heavy oil are reduced and the sulfur is released as hydrogen sulfide. The hydrogen sulfide can be fed directly into the anode side of the electrochemical cell to produce sulfur and hydrogen or it can be passed to an oxidation zone containing an aqueous solution of an oxidized metal salt.

    摘要: This invention relates to the electrochemical conversion of dibenzothiophene type molecules of petroleum feedstreams to mercaptans that can then be removed, in one embodiment, by caustic extraction. In another embodiment, the mercaptans can be thermally decomposed, removing sulfur as hydrogen sulfide. The conversion of dibenzothiophenes to mercaptans is performed by electrochemical means without the required addition of hydrogen and in the substantial absence of water.
