    摘要: A method of producing catalyst powder of the present invention has a step of precipitating any one of a noble metal particle (5) and a transition metal particle (10) in a reversed micelle (1); a step of precipitating, in the reversed micelle (1) in which any one of the noble metal particle (5) and the transition metal particle (10) is precipitated, a porous support material (7) which supports the noble metal particle (5) and the transition metal particle (10); and a step of precipitating the other of the noble metal particle (5) and the transition metal particle (10) in the reversed micelle (1) in which any one of the noble metal particle (5) and the transition metal particle (10) is precipitated. By this method, it is possible to obtain catalyst powder capable of maintaining initial purification performance thereof even if being exposed to the high temperature.

    摘要: The present invention provides a catalyst suitably employed in a variety of hydrocarbon reforming processes and a hydrocarbon reforming process including employing the catalyst in production of hydrogen or synthesis gas. The hydrocarbon reforming catalyst of the present invention contains an alumina carrier containing cerium oxide and, carried on the carrier, component (a), component (b), and optional component (c), the component (a) being at least one platinum group element selected from among ruthenium, platinum, rhodium, palladium, and iridium; the component (b) being cobalt and/or nickel, the component (c) being an alkaline earth metal. When steam reforming, autothermal reforming, partial-oxidation reforming, or carbon dioxide reforming of hydrocarbons is performed through employment of the catalyst, hydrogen or synthesis gas can be produced.
