ABSTRACT:
A multiple-stage hydrocarbon steam reforming process for producing a methane-rich substitute natural gas. A portion of the first stage efluent is condensed, water is removed therefrom and the remainder is recycled to combine with the fresh charge stock to the first stage. Following one stage of methanation, or shift conversion, both steam and carbon dioxide are removed prior to effecting additional reactions in a second methanation stage.
