摘要： For producing methanol from a synthesis gas containing hydrogen and carbon oxides the synthesis gas is passed through a first, preferably water-cooled reactor in which a part of the carbon oxides is catalytically converted to methanol, and the resulting mixture containing synthesis gas and methanol vapor is supplied to a second, preferably gas-cooled reactor in which a further part of the carbon oxides is converted to methanol. The mixture withdrawn from the first reactor is guided through a gas/gas heat exchanger in which the mixture is cooled to a temperature below its dew point. Subsequently, methanol is separated from the gas stream in a methanol separator and withdrawn, while the remaining gas stream is supplied to the second reactor.
