Abstract

A method for conversion of carbon dioxide to carbon monoxide comprises: introducing a flow of a dehumidified gaseous source of carbon dioxide into a reaction vessel; and irradiating dried, solid carbonaceous material in the reaction vessel with microwave energy. Heating of the irradiated carbonaceous material drives an endothermic reaction of carbon dioxide and carbon that produces carbon monoxide. At least a portion of heat required to maintain a temperature within the reaction vessel is supplied by the microwave energy. Carbon monoxide thus produced is allowed to flow out of the reaction vessel.
