摘要：
Catalytic properties of monometallic Ni and bimetallic Ru-Ni supported on Al2O3, CaO-Al2O3, and MgO-Al2O3 have been studied in mixed reforming of methane. Physicochemical properties of the catalytic systems have been studied by X-ray diffraction, scanning electron microscopy with energy dispersive spectroscope and temperature-programmed reduction by hydrogen. It has been shown that, of all the studied samples, the highest conversion of methane and carbon dioxide is achieved in the presence of the Ru-Ni/MgO-Al2O3 bimetallic catalyst. Temperature-programmed reduction has confirmed the effect of hydrogen spillower from ruthenium to NiO. The formation of Ru-Ni alloy has also been found.
