用 TPR,TPD,TPO,TPMC(程序升温 CH4解离积炭 )和活性评价等手段研究了普通浸渍法与载体盐助分散浸渍法制得的 CH4/CO2 重整制合成气 Ni基催化剂的性能 .结果表明 ,用载体盐助分散浸渍制备的催化剂 Ni-O-Mg间作用较强 ,吸附 CO2 能力较大 ,CH4解离积炭量少 ,因此其稳定性及寿命较好 . The performance of Ni-based catalysts for CH4 / CO2 reforming of syngas was investigated by means of TPR, TPD, TPO, TPMC (temperature programmed CH4 dissociation coke deposition) and activity evaluation. The results show that Ni-O-Mg catalyst prepared by impregnation with carrier salt is more effective in adsorbing CO2 and less dissociating carbon in CH4, so its stability and life expectancy are better.
