Abstract
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 membraneand a second separation membranethat are made of different materials. When the first mixture gas is supplied at a temperature of 100° C. or higher, the first separation membraneseparates 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 membraneseparates water vapor that permeates through the second separation membraneby allowing water vapor to permeate selectively.
