Abstract:
1. A method of processing a hydrocarbon feed to remove undesired aromatic and non-aromatic organosulfur compounds comprising: subjecting the hydrocarbon feed to a hydrotreating process to thereby lower the content of labile organosulfur compounds and produce a hydrotreated effluent which contains refractory aromatic organosulfur compounds; conveying the hydrotreated effluent and an effective quantity of extraction solvent to an extraction zone to produce separating at least a substantial portion of the extraction solvent from the extract and retaining an aromatic-rich fraction; 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.
