Publication number: 20240141525Abstract: An electrosynthesis system is equipped with an electrolysis device that carries out electrolysis on carbon dioxide gas and water vapor, a synthesizing device that synthesizes a hydrocarbon gas from hydrogen gas and carbon monoxide gas that are generated by the electrolysis, and a control device. The control device adjusts a flow rate of the water vapor supplied to the electrolysis device, in a manner so that a first concentration ratio, which is a concentration ratio between the hydrogen gas and the carbon monoxide gas in a mixed gas discharged from the electrolysis device and containing the hydrogen gas and the carbon monoxide gas, becomes a predetermined target concentration ratio.Type: ApplicationFiled: October 26, 2023Publication date: May 2, 2024Inventors: Masahiro MOHRI, Kazuki YANAGISAWA, Misato MAKI, Hideaki YONEDA, Jumpei YOSHIDA
