VERFAHREN ZUR HERSTELLUNG VON METHANOL

Methanol is prepared by catalytic conversion of a synthesis gas mixture, containing hydrogen, carbon monoxide, carbon dioxide and/or water, at from 200 DEG to 320 DEG C. and under from 30 to 300 bar in adiabatic and/or isothermal reactions in the presence of a catalyst containing copper and zinc, by...

Zusammenfassung:Methanol is prepared by catalytic conversion of a synthesis gas mixture, containing hydrogen, carbon monoxide, carbon dioxide and/or water, at from 200 DEG to 320 DEG C. and under from 30 to 300 bar in adiabatic and/or isothermal reactions in the presence of a catalyst containing copper and zinc, by a process in which the fresh catalyst is reduced with a hydrogen-containing gas before the start-up of the process, and then the synthesis is started under conventional conditions and is continued until the formation of methanol in the reaction zone has declined substantially, after which the reaction is interrupted and the catalyst is regenerated.
