Document Type and Number:
WIPO Patent Application WO/2023/074769
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a gas processing device, a gas processing method, and a methane fermentation system which a low-cost and stable desulphurization process in the processing of hydrogen sulfide-containing gas, together with allowing efficient energy recovery and usage. In order to solve the problem, provided are: a gas processing device which comprises, for the processing of hydrogen sulfide-containing gas, a reaction part having a pair of electrodes, and a gas introduction part that introduces hydrogen sulfide-containing gas to an anode side of the reaction part, wherein the reaction part generates power and/or removes sulfur components by reaction of hydrogen sulfide; a gas processing method; and a methane fermentation system comprising the gas processing device.
