A process for the co-production of superheated steam and methane comp&pgr;sing reacting a gas containing carbon monoxide and hydrogen in a se&pgr;es of methanation regions to produce a product gas containing methane, wherein the gas containing carbon monoxide and hydrogen flows, in passing through the se&pgr;es of methanation regions, successively through at least a first internally cooled methanation region, cooling the first and second internally cooled methanation region with water, which water is vaporized in the first internally cooled methanation region to produce steam and which steam is subsequently superheated in the second internally cooled methanation region to produce superheated steam, wherein the internally cooled methanation regions comprise tubes filled with a methanation catalyst and a space surrounding the tubes. |
