    摘要: A process for producing a methane-containing gas mixture includes the steps of: (i) passing a first feed gas mixture including hydrogen and carbon dioxide through a bed of methanation catalyst to react a portion of the hydrogen with at least a portion of the carbon dioxide and form a methane-containing gas mixture containing residual hydrogen, (ii) adding an oxygen-containing gas to the methane-containing gas mixture containing residual hydrogen to form a second feed gas mixture, and (iii) passing the second feed gas mixture through a bed of an oxidation catalyst to react the residual hydrogen and oxygen to form a hydrogen depleted methane-containing gas mixture.
