Patent number: 6726853Abstract: The present invention relates to a catalyst for reforming that is employed when preparing a synthetic gas by reacting hydrocarbon such as methane with a reforming agent such as water, carbon dioxide, oxygen, air or the like. The present invention further relates to a process for producing a synthetic gas employing this catalyst for reforming. By employing the catalyst for reforming that is a mixed oxide having the composition expressed by the following formula in which the M and Co are in a highly dispersed state, it is possible to suppress precipitation of carbonaceous matters (carbon) when producing the synthetic gas. aM.bCo.cMg.dCa.eO (Where, a, b, c, d, and e are molar fractions, a+b+c+d=1, 0.0001≦a≦0.10, 0.0001≦b≦0.20, 0.70≦(c+d)≦0.9998, 0<c≦0.9998, 0≦d<0.9998, e=the number of oxygen necessary to maintain an electric charge balance with metallic elements.Type: GrantFiled: May 21, 2002Date of Patent: April 27, 2004Assignee: Sekiyushigen Kaihatsu Kabushiki KaishaInventors: Hideo Okado, Toshiya Wakatsuki, Kiyoshi Inaba, Hitomi Hirano

Patent number: 5750821Abstract: The following steps are conducted for producing a hydrocarbon having a carbon number of at least 2: a coupling step, in which a coupling feed gas containing methane and a gas containing oxygen are supplied to a conveying catalyst bed which is formed by an ascending stream which contains a catalyst, and then methane and oxygen are allowed to react so as to produce a coupling product gas; a catalyst separation step for separating the catalyst from the coupling product gas; and a catalyst feedback step for feeding back the thus-separated catalyst to the coupling step. Accordingly, the reaction system does not accumulate excessive heat, the combustion reaction as a side reaction is hindered, and the selectivity of the coupling reaction is enhanced. In addition, the yield of the hydrocarbon having a carbon number of at least 2 is improved.Type: GrantFiled: November 21, 1995Date of Patent: May 12, 1998Assignees: Japan National Oil Corporation, Sekiyushigen Kaihatsu Kabushiki Kaisha, Cosmo Research InstitueInventors: Makoto Inomata, Tsutomu Katagiri, Kozo Imura, Erli Sun

Patent number: 5354936Abstract: A method for preparing ethane and ethylene by reacting methane or a methane-containing natural gas in the presence of oxygen or an oxygen-containing gas, i.e., by partially oxidizing, at a temperature of 500.degree. through 1000.degree. C. using shellfishes or shells as a catalyst is disclosed. The oxidation coupling reaction of methane is controlled so as to remarkably increase the conversion ratio of methane and the selectivity of C.sub.2.sup.+ compounds. The waste matter abundantly released from food industries as well as easily accessible natural resources is used as a raw material of a catalyst for the reaction. The present method is extremely useful from the viewpoint of the recycling of waste as well.Type: GrantFiled: March 26, 1993Date of Patent: October 11, 1994Assignee: Sekiyushigen Kaihatsu Kabushiki KaishaInventors: Masami Yamamura, Hideo Okado, Naohide Tsuzuki, Kazutoshi Chaki, Toshiya Wakatsuki
