Abstract:
1. A hydrogen production apparatus comprising: a reformer configured to obtain a hydrogen-containing gas from a raw material for hydrogen production by utilizing a reforming reaction; a shift reactor configured to reduce the concentration of carbon monoxide in the gas obtained from the reformer by a shift reaction; a cooler configured to cool the gas obtained from the shift reactor; a heat exchange structure configured to heat the gas cooled by the cooler; and a preferential oxidation reactor comprising a preferential oxidation catalyst bed packed with a catalyst capable of promoting a preferential oxidation reaction which preferentially oxidizes carbon monoxide, the preferential oxidation reactor being configured to reduce the concentration of carbon monoxide in the gas heated by the heat exchange structure, wherein the cooler is provided downstream of the shift reactor, and the heat exchange structure and the preferential oxidation reactor are provided separately from and downstream of the cooler; and wherein the heat exchange structure and the preferential oxidation reactor are configured so that the gas cooled by the cooler is heated upstream of the preferential oxidation catalyst bed with the use of heat generated by the preferential oxidation reaction.
