A Ni-based catalyst supported by γ-Al2<\/sub>O3<\/sub> was prepared by impregnation method, and the catalyst was used in a low CO and CO2<\/sub> concentration methanation system. The effect of temperature, pressure and space velocity on the methanation reaction was investigated in an experimental fixed-bed reactor. The methanation reaction was operated at the conditions of 190-240°C, 3000-24000ml•g-1<\/sup>•h-1<\/sup> and 1.5-3.5MPa. The results show that temperature and space velocity play important role on the reaction. With the increase of reaction temperature the CO and CO2<\/sub> conversion increase and the selectivity of CH4<\/sub> increase. And with the increase of the space velocity the conversion of CO and CO2<\/sub> and the selectivity of CH4<\/sub> decrease sharply.<\/p>\r\n","references":"[1]\tP. Sabatier, and J. B.
