| 摘 要： | 采用等体积浸渍法制备了Ni-Fe/γ-Al2O3双金属催化剂和Ni/γ-Al2O3、Fe/γ-Al2O3单金属催化剂，在连续流动微反装置上考察了催化剂的CO甲烷化催化活性，采用XRD、N2物理吸附、H2-TPR、H2-TPD和TPSR等手段对催化剂进行表征。结果表明，Ni-Fe/γ-Al2O3双金属催化剂中Ni、Fe之间产生了明显的相互作用，还原后催化剂中形成Ni-Fe合金，对氢气吸附量显著增加。在CO体积分数为0.5%、空速5000h-1、常压的反应条件下，Ni-Fe/γ-Al2O3双金属催化剂表现出高的甲烷化活性，220℃时将CO完全转化为甲烷。

| Abstract: | Bimetallic Ni-Fe/γ-Al2O3 catalyst and monometallic Ni/γ-Al2O3, Fe/γ-Al2O3 catalysts were prepared by wet impregnation method; they were characterized by XRD, N2 physisorption, H2-TPR, H2-TPD and TPSR. The activity of these catalysts in CO methanation was investigated in a fixed-bed continuous flow reactor. A significant Ni-Fe interaction is observed in the bimetallic Ni-Fe/γ-Al2O3 catalyst; Ni-Fe alloy is formed during reduction, which can promote the adsorption of hydrogen. Under the reaction conditions of 0.5% CO, GHSV of 5000h-1 and atmosphere pressure, the bimetallic Ni-Fe/γ-Al2O3 catalyst exhibits high catalytic activity; CO can be completely converted into methane at 220℃. |
