The desulfurizing agent for super depth oxidation desulfurization and the oxidation desulfurization manner which uses that

摘要

P To provide a desulfurizing agent capable of efficiently removing organic sulfur compounds contained in a liquid oil, particularly hardly decomposable organic sulfur compounds and provide a desulfurization method using the desulfurizing agent. PSOLUTION: The desulfurizing agent comprises (1) a solid catalyst consisting of the following components (a) and (b) and (2) urea peroxide, wherein the component (a) is at least one component selected from the group consisting of metal oxides, acids of these oxides and salts of the acids of these oxides, isopolyacids of metals and salts thereof and heteropolyacids of metals and salts thereof (wherein the metal is selected from the group consisting of tungsten and molybdenum and vanadium) and the component (b) is hydrotalcite. The desulfurization method comprises putting into contact a liquid oil containing organic sulfur compounds with the above desulfurizing agent. PCOPYRIGHT: (C)2008 and JPO& INPIT
