Title:
メタンの製造装置及びそれを用いたメタンの製造方法
Document Type and Number:
Japanese Patent JP6786054
Kind Code:
B2
Abstract:
An apparatus of producing methane from a CO-containing gas comprises:at least two first reactors with a COstorage-reduction catalyst having a COstorage capacity and a methane generation ability disposed in parallel;at least one second reactor provided with a methanation catalyst;means for supplying purge gas; andmeans for supplying reducing gas, whereinthe means for supplying purge gas and for supplying reducing gas are disposed upstream of the first reactors,the second reactor is disposed downstream of the first reactors, anda gas outlet of one of the first reactors is connected to a gas inlet of at least one different one of the first reactors via a purge gas recirculation line which supplies a purge gas emitted from the gas outlet of the one first reactor into the gas inlet of the different first reactor.
