Methanation of Carbon Dioxide on Supported Iron Catalysts
Abstract:
Fe catalysts supported on inorganic oxides have been prepared by impregnation method.Their catalytic activities for the methanation of carbon dioxide are investigated.The results indicate that the oxide supports, in order of influence on the activity of Fe catalyst are titania > zirconia > sepiolite > alumina > silica.Both the conversion of carbon dioxide and the selectivity of methane strongly depend on the GHSV and the composition of feedstock.The ammonia treatment of Fe catalysts before calcination favors the methanation reaction.The introductions of other Ⅷ group or non-Ⅷ group metals influence the catalytic activities effectively.
