Carbon dioxide treatment device and method of producing carbon compound

Abstract

What is provided is a carbon dioxide treatment device having high energy efficiency for recovering and reducing carbon dioxide, and a method of producing a carbon compound using the carbon dioxide treatment device. In a carbon dioxide treatment device (100) including a recovery device (1) that recovers carbon dioxide, an electrochemical reaction device (2) that electrochemically reduces carbon dioxide recovered by the recovery device (1), and a homologation reaction device (4) that increases the number of carbons by multimerizing ethylene generated when carbon dioxide is reduced in the electrochemical reaction device (2), and in an absorption unit (12) of the recovery device (1), carbon dioxide gas is absorbed into an absorption liquid (A1), an absorption liquid (A2) that has absorbed carbon dioxide is heated in a discharge unit (13), and a carbon dioxide gas (G3) is discharged, and heat generated in a multimerization reaction in a homologation reaction device (4) is used to heat the absorption liquid (A2) in the discharge unit (13).
