Abstract
In a reforming reactor operated with reactor outlet temperatures from 600.degree. to 1300.degree. C. and under a pressure from 10 to 100 bars, a methane-containing hydrocarbon gas is reacted with oxygen and water vapor. The reforming reactor is additionally fed with a high-hydrogen gas, which contains free hydrogen. The raw synthesis gas withdrawn from the reforming reactor is mainly composed of hydrogen, carbon monoxide and carbon dioxide. Without a removal of carbon dioxide from the raw synthesis gas, a synthesis gas is produced, which is suitable for the methanol synthesis and in which the concentrations of the components H.sub.2, CO and CO.sub.2 have a molar ratio (H.sub.2 -CO.sub.2): (CO+CO.sub.2), called the stoichiometric number, from 1.97 to 2.2. In case of need, the stoichiometry number can be adjusted by adding hydrogen to the raw synthesis gas coming from the reforming reactor.
