Patent ID: 8741128

Claim:
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 an extract containing a major proportion of the aromatic content of the hydrocarbon feed and a portion of the extraction solvent and a raffinate containing a major proportion of the non-aromatic content of the hydrocarbon feed and a portion of the extraction solvent; 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.
