TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Absorbent: The absorbent is a porous inorganic oxide chosen from silica, alumina, silica-alumina, zeolite, titania, zirconia, magnesia, silica-magnesia, clay, diatomaceous earth, activated carbon and insoluble synthetic resin. The secondary desulfurizing agent is a catalyst which has porous support carrying nickel, silver, chromium, manganese, iron, cobalt, zinc, lead, iridium, platinum, ruthenium, rhenium and/or gold. Preferred Conditions: The absorbent is used at -40 degrees C to 100 degrees C. The secondary desulfurizing agent is used at -40 degrees C to 220 degrees C.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: After processing the hydrocarbon containing organosulfur compound by oxidizing agent in reaction vessel, the hydrocarbon is made to contact with an absorbent, and simultaneously distilled or solvent extracted, to remove organosulfur compound. The remaining organosulfur compound in hydrocarbon is further absorbed and removed by secondary desulfurizing agent. Preferred Composition: The hydrocarbon containing organosulfur compound is chosen from liquefied petroleum gas (LPG), town gas, naphtha, gasoline, kerosene, light oil, fuel oil, asphaltene, oil-sand oil, coal liquid, petroleum group heavy oil, shale oil, GTL, waste-plastic oil and bio fuel. SPECIFIC COMPOUNDS - The oxidizing agent used for processing hydrocarbon, is chosen from oxygen, air, nitrogen tetroxide, ozone, chlorine, bromine, meta-sodium periodide, potassium dichromate, potassium permanganate, chromic acid anhydride, hypochlorous acid, hydrogen peroxide, peracetic acid, hydrogen peroxide and acetic acid, performic acid, hydrogen peroxide and formic acid, meta-chloro perbenzoic acid, hydrogen peroxide and meta-chloro benzoic acid, chloroacetic acid, hydrogen peroxide and chloroacetic acid, dichloroacetic acid, hydrogen peroxide and dichloroacetic acid, trichloroacetic acid, hydrogen peroxide and trichloroacetic acid, trifluoroacetic acid, hydrogen peroxide and trifluoroacetic acid, meta-sulfonic acid, hydrogen peroxide and meta-sulfonic acid, hydrogen peroxide and salicylic acid, persulfuric acid, and hydrogen peroxide and sulfuric acid. The solvent used for solvent extraction process, is water, acetonitrile, propionitrile, butyronitrile, nitromethane, nitroethane, nitropropane, nitrobenzene, dimethyl sulfoxide, N,N'-dimethyl formamide, N,N'-dimethyl acetamide, N-methyl pyrrolidone, trimethyl phosphoric acid ester, triethyl phosphoric acid ester, hexamethyl phosphorus acid amide, phosphorane, methanol, ethanol, propanol, butanol and/or acetone.
