tially carbon oxides and methane. The purified hydrogen is supplied to a hydrogenating plant, which is operated at temperatures in the range of 250 degrees to 500 degrees C. and pressures of 200 to 400 bars. High-hydrogen gas from the hydrogenating plant flows in a pipeline through a heater and is then recycled to the hydrogenating plant. The heater consists of a fuelfired reheater, in which the separated gas is used as a fuel. The pipeline in which the high-hydrogen gas is recycled between the hydrogenating plant and the heater consists of an alloy steel, in which the carbon is combined in carbides with at least one of the alloying constituents chromium, m o l y b d e n u m , tungsten or vanadium.
