Abstract:
1. A method of processing a hydrocarbon feed to remove undesired aromatic and non-aromatic organosulfur compounds comprising: subjecting the hydrocarbon feed and an effective quantity of extraction solvent to an extraction zone to produce separating at least substantial portion of the extraction solvent from the raffinate and retaining an aromatic-lean fraction; separating at least substantial portion of the extraction solvent from the extract and retaining an aromatic-rich fraction; subjecting the aromatic-lean fraction to a hydrotreating process to thereby reduce the sulfur content; contacting the aromatic-rich fraction with an oxidizing agent and an oxidizing catalyst to convert aromatic organosulfur compounds to oxides and produce an oxidized aromatic rich fraction; and separating the oxidizing agent and oxidizing catalyst from the oxidized aromatic-rich fraction, wherein the oxidizing agent is separated by solvent extraction.
