PP-II-60NEW URANIUM OXIDE CATALYSTS FOR HYDROGEN PRODUCTION BYPARTIAL OXIDATION AND REFORMING OF METHANEKuznetsov V.V., Ismagilov Z.R., Shikina N.V., Lazarchuk V.V. 1 , Balakhonov V.G. 1 ,Matyuha V.A. 1 , Drobyaz A.I. 2 , Khlytin A.L. 2Boreskov Institute of Catalysis SB RAS, Novosibirsk, Russia1 Siberian Chemical Complex, Seversk, Russia2 Plant of Chemical Concentrates, Novosibirsk, RussiaE-mail: zri@catalysis.ruNew uranium oxide based catalysts containing different amount of uranium weresynthesized, characterized and tested in the reactions of methane steam and carbon dioxidereforming, and methane partial oxidation. It was shown that introduction of uranium intoNi/Al 2 O 3 catalyst can significantly improve the catalytic properties of commercial Nicontainingcatalyst by an increase of hydrogen yield and a decrease of carbon formation. Theuranium containing catalysts are very prospective to hydrogen production from methane andcan be applied to the processes of hydrogen energy, petrochemistry and other processes.Resent investigations in the fields of catalysis and new generation materials show that theuse of uranium oxides as catalysts is very urgent today due to specific chemical and physicalproperties of uranium oxide materials. The most prospective peculiarity of uranium oxides istheir high catalytic properties in the reactions of hydrogen or syn-gas production from lightand heavy hydrocarbons by catalytic reforming or partial oxidation.Despite the fact that chemistry of uranium containing compounds is highly studied, thereis very restrictive information on catalytic properties of uranium oxide compounds.The present work is devoted to the study of catalytic and physico-chemical properties ofuranium oxides – nickel mixed catalysts in the reactions of methane partial oxidation andsteam and dry methane reforming to produce syn-gas.The alumina supported catalysts containing 10 wt.% of Ni and different uranium oxideamount (from 0 to 30 wt.%) were synthesized and tested in the reactions of methane steamand carbon dioxide reforming, and partial oxidation of methane.It was show that the introduction of U into Ni catalysts results in the activity increase: thehigher the U content the higher the activity of the catalysts in all studied reactions. Theoptimum catalyst providing the highest hydrogen yield is the catalyst containing 15%uranium.272
