Title:
METHANATION REACTION DEVICE
Document Type and Number:
Japanese Patent JP2013136538
Kind Code:
A
Abstract:

To provide a methanation reaction device, capable of avoiding abrupt rise of temperature within the device, in a reaction of converting a raw material gas including much carbon dioxide into methane by the methanation reaction.

This methanation reaction device for producing a gas including methane by feeding hydrogen to the raw material gas including carbon dioxide comprises: a first reactor of feeding the raw material gas and a part of hydrogen; a second reactor of feeding the rest of hydrogen to the reaction mixed gas sent from the first reactor, and adjusting the amount of hydrogen necessary for the reaction; and a third reactor of adjusting the composition of produced gas sent from the second reactor, where the reaction temperature of the first reactor is adjusted by adjusting the amount of hydrogen fed to the reactor.
