Ni-Fe/γ-Al2O3双金属催化剂的制备及其CO甲烷化性能研究
Preparation of bimetallic Ni-Fe/γ-Al2O3 catalyst and its activity for CO methanation
摘要
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 5 000 h-1 and atmosphere pressure, the bimetallic Ni-Fe/γ-Al2O3 catalyst exhibits high catalytic activity; CO can be completely converted into methane at 220 ℃.关键词
