Muller, W D; Moller, F W; Jockel, H

A gas which can be substituted for natural gas is produced from a raw gas containing hydrogen and carbon oxides which is produced by the gasification of coal, tar, or heavy residual oils under superatmospheric pressure. The raw gas is cooled, purified to remove catalyst poisons, particularly sulfur compounds, and then subjected to methanation and at least two stages in contact with nickel catalysts under pressures of 5-100 bars and at temperatures in the range of 200-500/sup 0/C. The product gas from the preceding methanation stage is reacted in the last methanation stage in contact with a catalyst which is indirectly cooled by a gas flowing in a countercurrent to the gas to be reacted. 5 claims, 4 figures.
