CARBON DIOXIDE TREATMENT APPARATUS, CARBON DIOXIDE TREATMENT METHOD, AND METHOD OF PRODUCING CARBON COMPOUND

An object of the present invention is to provide a carbon dioxide treatment apparatus, a carbon dioxide treatment method, and a method of producing carbon compounds, which have high energy efficiency from carbon dioxide capture to reduction and a high carbon dioxide loss reduction effect. In a carbon dioxide treatment apparatus including: a capturing device that captures carbon dioxide; and an electrochemical reaction device that electrochemically reduces carbon dioxide, an absorption unit of the capturing device brings an electrolytic solution A composed of a strong alkaline aqueous solution and carbon dioxide gas into contact with each other to dissolve carbon dioxide in the electrolytic solution A and absorb the carbon dioxide, supplies an electrolytic solution B that has absorbed carbon dioxide between the cathode and the anode of the electrochemical reaction device , and electrochemically reduces the dissolved carbon dioxide in the electrolytic solution at the cathode.
