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.

摘要： In a gas separation apparatus that separates carbon dioxide and water vapor from a first mixture gas containing a predetermined major component gas, carbon dioxide, and water vapor, the energy utilization efficiency thereof is improved. Also, by utilizing the function of this gas separation apparatus, a membrane reactor and a hydrogen production apparatus exhibiting high energy utilization efficiency are provided. The gas separation apparatus is constructed to include a first separation membrane 33 and a second separation membrane 34 that are made of different materials. When the first mixture gas is supplied at a temperature of 100° C. or higher, the first separation membrane 33 separates a second mixture gas containing carbon dioxide and water vapor that permeate through the first separation membrane by allowing carbon dioxide and water vapor to permeate selectively. When the second mixture gas is supplied, the second separation membrane 34 separates water vapor that permeates through the second separation membrane 34 by allowing water vapor to permeate selectively.
