TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The hydrocarbon reforming catalyst comprises an oxide, in which the catalyst component is impregnated into the oxide. The surface area of the oxide carrier is 10-800 m2/g. The thermal conductivity of the thermally conductive material is 15-600 Wm1K-1 at room temperature. The oxide carrier comprises aluminum oxide, silicon dioxide, titanium dioxide, zirconium dioxide, and/or cerium oxide. The thermally conductive material comprises aluminum, carbon, copper, cobalt, iron, nickel, zinc and/or manganese. The active catalyst component is formed of ruthenium, platinum, rhodium, cobalt, nickel, and/or palladium. The oxide carrier is present at 10-90 wt.% of the total weight of the oxide carrier and the thermally conductive material. The active catalyst component is present at 0.1-20 wt.%. The average particle size of the thermally conductive material is 0.1 microns -5 mm, and the average particle size of the oxide carrier is 0.1 microns to 5 mm. In the method, the mixing weight ratio of the thermally conductive material and the oxide carrier is 1:9-9:1. The catalyst component is not formed of a shell on the oxide. Preferred Method: The impregnating of the active catalyst component in the mixture is performed using deposition-precipitation, co-precipitation, wet impregnation, sputtering, gas-phase grafting, liquid-phase grafting or incipient-wetness impregnation. The drying of the resultant is performed at 100-160degreesC for 3-5 hours. The heat treating of the dried resultant is performed at 500-750degreesC for 2-5 hours. The catalyst component is impregnated by being interstitially dispersed. EXAMPLE - Ruthenium oxide monohydrate (0.286 g) was dissolved in distilled water (3.5 ml) to prepare an aqueous ruthenium solution. The aqueous ruthenium solution was impregnated in aluminum oxide carrier (7 g) using an incipient-wetness impregnation method. The resultant was dried at 120degreesC for 4 hours. Aluminum powder and the dried resultant were mixed at a weight ratio of 3:7 to obtain a mixture of aluminum powder and aqueous ruthenium solution (10 g). The amount of ruthenium in the formed catalyst was regulated to 1.4 wt.%. The mixture was heat treated at 520degreesC for 4 hours in air to prepare a pelletized hydrocarbon reforming catalyst.
