Title:
CARBON DIOXIDE TREATMENT APPARATUS, CARBON DIOXIDE TREATMENT METHOD, AND METHOD FOR PRODUCING CARBON COMPOUND
Document Type and Number:
Japanese Patent JP2022131811
Kind Code:
A
Abstract:
To provide a carbon dioxide treatment apparatus, a carbon dioxide treatment method and a method for producing a carbon compound, which attain a high energy efficiency from recovery to reduction of carbon dioxide and a high carbon dioxide loss reduction effect.SOLUTION: A carbon dioxide treatment apparatus 100 comprises a recovery device 1 for recovering carbon dioxide and an electrochemical reaction device 2 for electrochemically reducing carbon dioxide. In the apparatus, an electrolyte A composed of a strong alkaline aqueous solution is brought into contact with carbon dioxide gas in an absorption part 12 of the recovery device 1 so that carbon dioxide is dissolved and absorbed in the electrolyte A, and an electrolyte B having absorbed carbon dioxide is supplied between a cathode and an anode of the electrochemical reaction device 2 so that dissolved carbon dioxide in the electrolyte is electrochemically reduced at the cathode.SELECTED DRAWING: Figure 1
