CARBON-MANUFACTURING METHOD, CARBON-MANUFACTURING DEVICE, CARBON DIOXIDE RECOVERY METHOD, AND CARBON DIOXIDE RECOVERY DEVICE

WIPO Patent Application WO/2023/157509

A1

The present invention is a carbon-manufacturing method and a carbon-manufacturing device. In the carbon-manufacturing method, a positive electrode 17 and a negative electrode 15 are immersed in a molten salt 13, a voltage is applied to the positive electrode 17 and the negative electrode 15, carbon dioxide is fed, and solid carbon is manufactured by electrolysis. A liquid metal including at least one element selected from the group consisting of tin, bismuth, antimony, zinc, cadmium, lead, indium, and gallium is used as the negative electrode 15, the carbon dioxide being blown into the liquid metal. The present invention can also be used as a carbon dioxide recovery method and a carbon dioxide recovery device for recovering carbon dioxide from a carbon-dioxide-containing gas.
