Methanol is catalytically produced from a synthesis gas which contains H2, CO and CO2 in a synthesis reactor at temperatures from 220 DEG to 300 DEG C. and under a pressure in the range from 20 to 120 bars. A product mixture which contains methyl formate is withdrawn from the synthesis reactor and is cooled to temperatures in the range from 20 DEG to 60 DEG to provide a condensate which contains methanol, water and methylformate. A gas mixture which contains H2, CO and CO2 is formed at the same time. A fraction which comprises 10 to 100% by weight methyl formate is separated from the condensate and is admixed with the synthesis gas which is fed to the synthesis reactor. |
