Abstract
A method for producing an energetic gas from carbon dioxide includes the steps of: impregnating a plurality of alumina particles into a nickel-based aqueous solution to form a crude product, followed by subjecting the crude product to a drying treatment and then to a calcination treatment at a temperature ranging from 550° C. to 650° C., so as to obtain a supported catalyst; activating the supported catalyst with hydrogen, so as to obtain an activated supported catalyst; and subjecting hydrogen and carbon dioxide to a methanation reaction at a total gas hourly space velocity ranging from 4000 hto 5000 hin the presence of the activated supported catalyst, so as to form methane serving as an energetic gas.
