摘要：

The co-methanation of carbon dioxide containing syngas was carried out on Al2O3 supported NixFe1−x (x is 0.1, 0.3, 0.5, 0.7 and 0.9) catalysts for synthetic natural gas (SNG) production. The catalysts were prepared by wet-impregnation method taking 20 weight percent of the metallic component over the support, and its characteristics were analyzed by BET surface area, XRD and H2-TPR. The maximum carbon conversion and CH4 selectivity are achieved on Ni0.7Fe0.3/Al2O3 catalyst. Further, increase of Fe content led to enhancing the water gas shift reaction and hydrocarbon formation.
