TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Support: The zeolite-type support is a crystalline silicate of formula: (1plus minus0.8)R2O.(aM2O3.bLO.cAl2O3).ySiO2.R=alkali metal or H;M=group 8 element, rare-earth element, titanium, vanadium, chromium, niobium, antimony and/or gallium;L=magnesium, calcium, strontium and/or barium;a=0 or more;b=0-20;a+c=1;andy=11-3000.The peak from the strongest peak to fifth position appears in the lattice space 3.65plus minus0.1 Angstrom , 3.75plus minus0.1 Angstrom , 3.85plus minus0.1 Angstrom , 10plus minus0.3 Angstrom and 11.2plus minus0.3 Angstrom in the powder X-ray diffraction using CuK alpha ray. Preferred Agent: De-sulfurizing agent (II) comprises a support and active-metal element(s) chosen from nickel, iron, copper, zinc, cobalt, manganese, tin and silver. Preferred Support: The support is titania, silica, alumina or zirconia. The support contains a complex oxide of two or more elements having high dispersibility. The complex oxide has a specific surface area of more than 100 m2/g. The complex oxide is titania-silica, titania-alumina, titania-zirconia, zirconia-alumina, titania-phosphorus pentoxide, titania-boria, and/or silica-alumina, with MO included with all combinations, where M is nickel, iron, copper, zinc, cobalt, manganese, tin and/or silver. The high dispersible support contains boehmite. Preferred Method: De-sulfurizing agent (II) is obtained by mixing precipitant aqueous solution heat-retained at preset temperature, element compound and/or aqueous solution of zinc, aluminum or chromium, producing an oxide deposit, dripping an aqueous solution containing copper, producing a complex oxide containing copper, and producing a complex oxide containing copper supporting nickel. The complex oxide is further baked and molded, and de-sulfurizing agent (II) is reduced. The precipitation-reagent aqueous solution is sodium carbonate or sodium hydrogen carbonate.    TECHNOLOGY FOCUS - METALLURGY - Preferred Metal: The catalytically active metal is element(s) chosen from elements of groups 4-12.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Fuel: The fuel gas contains compound(s) chosen from 1-12C hydrocarbon group gas. Preferred Conditions: De-sulfurization is carried out at normal temperature to 500degreesC, and the de-sulfurization temperature of de-sulfurization portion (II) is 70-500degreesC. De-sulfurization portion (II) is contained in the reformer.
