Zusammenfassung:A method for producing methanol, allowing the temperature of the catalyst layer to fall within an appropriate temperature range, reducing the amount of energy used, and achieving a higher carbon yield. Specifically, provided is a method for producing methanol, wherein in a synthesis loop including at least two synthesis steps and two separation steps, a first mixed gas is obtained by mixing the final unreacted gas with a fraction of the make-up gas, methanol is synthesized from the first mixed gas after preheating, a first unreacted gas is separated from the obtained first reaction mixture, a final mixed gas is obtained by finally mixing the unreacted gas and a fraction of the make-up gas, the final mixed gas after preheating is further increased in pressure and then methanol is synthesized, a final unreacted gas is separated from the obtained final reaction mixture, and the reaction temperature of the catalyst layer is controlled by the indirect heat exchange with pressurized boiling water.
