Abstract

A process for carrying out a carbon monoxide shift reaction is provided. In the implementation of the carbon monoxide shift reaction, including the conversion of carbon monoxide and water into carbon dioxide and hydrogen, this conversion takes place in the liquid phase and involves separation of the product gases carbon dioxide and/or hydrogen, where as a first solvent dry methanol is used, for the absorption of carbon monoxide with simultaneous formation of a methyl formate, as a second solvent, in the area of release of the product gases, water is used, for avoiding hydrogen losses in a carbon dioxide area.
