CO shift reaction apparatus and CO shift reaction method

摘要

Provided are: a CO shift reaction apparatus which suppresses decrease of the catalytic activity of a CO shift catalyst that contains molybdenum and prolongs the service life of the catalyst; and a CO shift reaction method which uses the CO shift reaction apparatus. A CO shift reaction apparatus for reforming carbon monoxide in a gas, which is characterized by being provided with at least: a reactor which is provided with at least a CO shift catalyst that contains molybdenum, a gas feed port for introducing the gas, a CO shift catalyst layer which is filled with the CO shift catalyst and through which the introduced gas passes, and a gas discharge port for discharging the gas that has passed through the CO shift catalyst layer; and a cooling means which cools the CO shift catalyst layer.
