TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Properties: The desulfurizing capability of desulfurizing agent (A) is higher than that of desulfurizing agent (B) w.r.t sulfide and disulfide. The desulfurizing capability of desulfurizing agent (B) is higher than that of desulfurizing agent (A) w.r.t carbonyl sulfide. The capacitance ratio of desulfurizing agents (A, B) in the desulfurizing layer is 0.1:0.9-0.9:0.1. The zeolite has a beta structure and/or a faujasite structure. The temperature of the desulfurizing layer is -20 to 100degreesC.Preferred Gas: The hydrocarbon-containing gas is natural gas, town gas, liquid petroleum gas, naphtha fraction and/or dimethyl ether.Preferred Agent: The desulfurizing agent (A) contains metal component chosen from silver, copper, nickel, zinc, manganese, iron, cobalt, alkali metal, alkaline earth metal and rare earth metal, along with zeolite. The desulfurizing agent (B) contains metal component chosen from silver, copper, nickel, zinc, manganese, iron, cobalt, aluminum, silicon, alkali metal, alkaline earth metal and rare earth metal.Preferred Catalyst: The partial-oxidation reforming catalyst, self-thermal reforming catalyst or steam reforming catalyst, is ruthenium type or nickel type catalyst. EXAMPLE - HSZ-930NHA (beta-form zeolite) (in g) (20) baked at 500degreesC, and an aqueous solution of silver nitrate (3.5) dissolved in water, were stirred for 4 hours and ion exchange was performed. The solid substance in the resulting solution was washed, filtered, dried at 120degreesC for 12 hours and baked at 400degreesC for 3 hours. Desulfurizing agent (A) containing silver (6 mass%) was obtained. Nickel sulfate-hexahydrate (730.2) and copper sulfate-pentahydrate (151.3) were dissolved in water at 80degreesC. Pseudo boehmite containing aluminum trioxide (67 mass%) was mixed with the resulting solution, and sulfuric acid aqueous solution (300 mL) was added, to obtain liquid (A) having pH of 2. Sodium carbonate (600) was dissolved in water (8 l), and heated at 800degreesC. Water glass (180.2) containing silicon (29 mass%) was added to obtain liquid (B). The liquids (A, B) were mixed at 80degreesC and stirred for 1 hour. After washing precipitated cake, the cake was filtered, dried at 120degreesC for 12 hours, and baked at 350degreesC or more for 3 hours. Desulfurizing agent (B) containing nickel (65 mass%) and copper (15 mass%) was obtained. The desulfurizing agent (A) was filled on upstream side of desulfurizing pipe having internal diameter of 9 nm, and desulfurizing agent (B) was filled on downstream side on pipe. Propane gas containing carbonyl sulfide, dimethyl sulfide, t-butyl mercaptan and dimethyl disulfide, each in an amount of 10 volume ppm, was circulated in desulfurizing pipe at normal pressure, for 6 hours, 11 hours, more than 15 hours and 15 hours, respectively. The exit gas contained more than 0.07 weight ppm of sulfur compound.
