Simulation for microwave heating of catalysts for CO2 reduction to CO

Using the reverse water gas shift reaction (RWGS) one can produce carbon monoxide from carbon dioxide with the help of a catalyst. As the reaction is endothermic external energy in form of heat has to be applied. In the project CO2RRECT (CO2-Reaction using Regenerative Energies and Catalytic Technologies) [1], one task is to construct an applicator where the heating of the catalysts for the reaction is done by microwaves at a frequency of 2.45 GHz. This paper describes the simulation of such an applicator.
