PROCESS OF PRODUCING METHANOL

摘要

Methanol is catalytically produced from a synthesis gas containing hydrogen and carbon oxides on copper-containing catalysts at pressures in the range from 20 to 120 bar and temperatures in the range from 130 to 350.degree.C. The synthesis gas is first of all passed through a first synthesis reactor, in which the catalyst is provided in tubes surrounded by water as a coolant which is boiling at an elevated pressure. From the first reactor a first mixture containing gases and methanol vapor is withdrawn and passed through a second synthesis reactor. In the second reactor the catalyst is cooled with synthesis gas.
