FIELD: process engineering.

SUBSTANCE: invention relates to carbon oxide catalyst, to method of manufactured gas production, to method of producing carbon dioxide reforming catalyst and carrier for said catalyst. Said catalyst converts initial hydrocarbon gaseous stock by carbon dioxide and is used for production of synthesis gas containing carbon monoxide and hydrogen. Note here that carbon dioxide reforming catalyst comprises main component representing mix of carrier containing carbonate of, at least, one alkaline-earth metal selected from the group consisting of Ca, Sr and Ba, and catalytic metal to promote reaction of decomposition of initial hydrocarbon gaseous stock. Method of producing carbon dioxide reforming catalyst comprises stages of mixing carrier containing carbonate of, at least, one alkaline-earth metal selected from the group consisting of Ca, Sr and Ba, titanium oxide and catalytic metal to promote reaction of decomposition of initial hydrocarbon gaseous stock and calcination to produce alkaline-earth metal composite oxide/Ti that can absorb carbon dioxide, and reaction of carbon dioxide absorption by said alkaline-earth metal composite oxide/Ti. Method of producing carbon dioxide reforming catalyst comprises stage of calcination in the presence of barium carbonate of, at least, one material selected from (a) wet ceramic film, (b) wet ceramic film wastes, (c) laminar wet ceramic film wastes and (d) those of wet ceramic film precursors. Note here that, at least, one of (a) to (d) is used in production of electronic component and, at least one of (a) to (d) contains, at least, one alkaline-earth metal selected from group consisting of Ca, Sr, Ba, and Ti at alkaline metal-to-Ti ratio making 0.9-1.1 that comprises the perovskite-structure metal as the main substance and catalytic metal. Method of producing synthesis gas comprising carbon monoxide and hydrogen in carbon dioxide reforming of gaseous hydrocarbon initial stock comprises the stages of carbon dioxide reforming of gaseous hydrocarbon initial stock containing methane as main component in using aforesaid carbon dioxide reforming catalyst and carbon dioxide reforming catalyst carrier used for production of synthesis gas containing carbon monoxide and hydrogen via reforming of gaseous hydrocarbon initial stock in using carbon dioxide. Note here that said carrier comprises carbonate of, at least, one alkaline-earth metal selected from the group consisting of Ca, Sr and Ba.

EFFECT: catalyst facilitates reaction of gaseous hydrocarbon initial stock with carbon dioxide and efficient production of hydrogen and carbon monoxide.
