英文摘要 | National Basic Research Program of China (973 Program) [2010CB226903]; Metal-oxide-modified NiO/Al2O3 catalysts for methanation of CO were prepared using a modified grinding-mixing method and characterized using X-ray diffraction, transmission electron microscopy, N-2 adsorption-desorption isotherms, temperature-programmed reduction by H-2, temperature-programmed desorption by H-2, Raman spectroscopy, and X-ray photoelectron spectroscopy. The results show that the activity of an MgO-modified NiO/Al2O3 catalyst is better than those of NiO/ZrO2-Al2O3 and NiO/SiO2-Al2O3 in the reaction temperature range 300-700 degrees C. The incorporation of a metal oxide into NiO/Al2O3 was found to weaken Ni-Al interactions, leading to generation of large numbers of active Ni species, and this was confirmed to be responsible for the improvement in the performances of the catalysts in the methanation reaction.
