摘要：
The present invention provides a CO shift conversion device and a CO shift conversion method which improves CO conversion rate without increasing usage of a shift conversion catalyst. A CO shift conversion device includes: a CO shift converter 10 having a catalyst layer 5 composed of a CO shift conversion catalyst and performing CO shift conversion process on a gas flowing inside; and a CO2 remover 51 removing CO2 contained in a gas introduced. The catalyst layer 5 is composed of a CO shift conversion catalyst having a property that a CO conversion rate decreases with an increase of the concentration of CO2 contained in a gas flowing inside. The concentration of CO2 contained in a gas G0 to be processed is lowered by the CO2 remover 51 and, after that, the resultant gas is supplied to the CO shift converter 10 where it is subjected to the CO shift conversion process.
