Co-methanation of CO and CO2 on the NiX-Fe1−X/Al2O3 catalysts; effect of Fe contents

The co-methanation of carbon dioxide containing syngas was carried out on Al 2 O 3 supported Ni x Fe 1− 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...

Zusammenfassung:The co-methanation of carbon dioxide containing syngas was carried out on Al 2 O 3 supported Ni x Fe 1− 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 H 2 -TPR. The maximum carbon conversion and CH 4 selectivity are achieved on Ni 0.7 Fe 0.3 /Al 2 O 3 catalyst. Further, increase of Fe content led to enhancing the water gas shift reaction and hydrocarbon formation.
