Catalyst system for catalyzing the water gas shift reaction

摘要

A method for carrying out the water gas shift reaction by use of a homogeneous catalyst system containing rhodium carbonyl iodide in a water/acetic acid solvent is described. The catalyst system can be formed from RH (CO).sub.2 Cl!.sub.2, aqueous HI and glacial acetic acid. When a reactor is charged under 250-400 torr of CO at 90° C catalysis of the water gas shift reaction results.
