Abstract

The water-gas shift reaction is subject to thermodynamic limitation, i.e., CO conversion increases with decreasing temperature. Thus, it is preferential to keep temperatures as low as possible at reasonable kinetic rates. In this work, the performance of a ruthenium-based supported ionic liquid phase catalyst is shown for the water-gas shift reaction at ultralow temperature. Furthermore, a model for the intrinsic kinetics of the water-gas shift reaction using this supported ionic liquid phase catalyst is presented. For this purpose, a formal kinetic power law and a mechanistic general catalytic cycle kinetic approach were applied. Supported ionic liquid phase catalysts with filling levels up to 30 % were prepared. For filling levels < 13 %, internal mass transport limitations do not occur and intrinsic kinetics prevail.
