TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The oxide support comprises at least one oxide comprising aluminum oxide, silicon dioxide, zirconium oxide, titanium dioxide and yttria stabilized zirconia. The metal oxide comprises at least one oxide comprising manganese oxide (preferred), tin oxide, cerium oxide, rhenium oxide, molybdenum oxide or tungsten oxide. The alkali metal or alkali earth metal comprises at least one metal, comprising lithium, sodium, potassium (preferred), magnesium or calcium. The metal oxide is distributed on or in a layer including the nickel. The nickel is present at 1-40 parts by weight based on 100 parts by weight of the hydrocarbon reforming catalyst. The metal in the metal oxide is present at 0.5-20 parts by weight based on 1 part by weight of nickel. The alkali metal or alkali earth metal is present at 0.1-20 parts by weight based on 100 parts by weight of the hydrocarbon reforming catalyst. The carbon deposition rate of the hydrocarbon reforming catalyst is not less than 10%, preferably not less than 5%. Preferred Method: The loading of the nickel, the loading of the metal oxide, and the loading of the alkali metal or alkali earth metal are each performed independently by deposition precipitation, co-precipitation, wet impregnation, sputtering, gas-phase grafting, liquid-phase grafting or incipient-wetness impregnation. The loading of the nickel, the loading of the metal oxide, and the loading of the alkali metal or alkali earth metal, further comprises performing a heat-treatment process at 500-750 degrees C for 2-5 hours. EXAMPLE - Aluminum oxide support (100 g) was impregnated with potassium nitrate (18.66 g) as a potassium precursor so that the amount of potassium in the final hydrocarbon reforming catalyst was 6 wt.%. The resultant mixture was dried at 120 degrees C for 4 hours and then, sintered at 700 degrees C for 2 hours in an air atmosphere to give a first sintered product. Then, the first sintered product was impregnated with nickel(II) nitrate hexahydrate (30.4 g) as a nickel precursor so that the amount of nickel in the final hydrocarbon reforming catalyst was 5 wt.%. The resultant mixture was dried at 120 degrees C for 4 hours, and then sintered at 700 degrees C for 2 hours in an air atmosphere to give second sintered product. Then, the second sintered product was impregnated with manganese (II) nitrate hexahydrate (46.77 g) as a manganese precursor so that the weight ratio of manganese/nickel was 1:1. The resultant mixture was dried at 120 degrees C for 4 hours, and then sintered at 700 degrees C for 2 hours in an air atmosphere to give hydrocarbon reforming catalyst comprising manganese oxide/nickel/aluminum oxide.
