Abstract
A process for carrying out simultaneous reaction and separation of desired products in a single unit operation is described. It uses a fixed packed column of an admixture of a catalyst and a sorbent that selectively removes a reaction by‐product from the reaction zone. The sorbent is periodically regenerated by using the principles of pressure‐swing adsorption. The process steps allow direct production of the desired product at high purity and at the reaction pressure. High conversion of the reactants to products in an endothermic, equilibrium‐controlled reaction can be achieved while operating the reaction at a substantially lower temperature than would be necessary by a plug‐flow reactor packed with the catalyst alone. The equilibrium‐controlled reverse water‐gas shift reaction for the production of carbon monoxide is experimentally evaluated as a proof of the concept.
