Abstract

A method for the synthesis of methanol includes the steps of feeding a hydrogen-containing stream from a hydrogen recovery stage into a synthesis gas stream containing hydrogen and carbon oxides, and feeding the synthesis gas stream to a primary reactor stage for the catalytic and partial conversion of the synthesis gas stream into a gas mixture containing water, methanol, and residual gas, and further including the step of feeding a first portion of the residual gas to the hydrogen recovery stage for separation into the hydrogen-containing stream and a waste gas stream. The method is characterized in that a second portion of the residual gas is fed to a secondary reactor stage for further catalytic and at least partial conversion into a methanol-containing product stream.
