Patent number: 8343456Abstract: A hydrocarbon reforming catalyst which maintains carrier strength even after a long-term thermal history and which exhibits high catalytic activity is prepared by causing at least one noble metal component selected from among a ruthenium component, a platinum component, a rhodium component, a palladium component, and an iridium component to be supported on a carrier containing manganese oxide, alumina, and at least one compound selected from among lanthanum oxide, cerium oxide, and zirconium oxide, or a carrier containing silicon oxide, manganese oxide, and alumina. By use of the reforming catalyst, hydrogen is produced through steam reforming (1), autothermal reforming (2), partial-oxidation reforming (3), or carbon dioxide reforming (4). A fuel cell system is constituted from a reformer employing the reforming catalyst, and a fuel cell employing, as a fuel, hydrogen produced by the reformer.Type: GrantFiled: December 28, 2009Date of Patent: January 1, 2013Assignee: Idemitsu Kosan Co., Ltd.Inventors: Yoshimi Kawashima, Hiroshi Ohashi

Patent number: 6046128Abstract: A method of manufacturing a catalyst for purifying exhaust gas, the catalyst including a pentasil-type crystalline aluminosilicate catalyst carrier carrying thereon a copper component and a phosphorus component. The method is characterized by adding the catalyst carrier into a solution containing a copper component and a phosphorus component, or a buffer and having a predetermined pH adjusted with ammonia, and subsequently adding an acid to the solution so as to adjust the pH of the solution to 7.0 or less, to thereby incorporate the copper component and the phosphorus component into the catalyst carrier.
