Abstract:
1. A hydrogen production apparatus comprising a reforming part for obtaining a hydrogen-containing gas by utilizing a reforming reaction from a raw material for hydrogen production, a shift reaction part for reducing the concentration of carbon monoxide in the outlet gas of the reforming part by shift reaction, and a selective oxidation reaction part having a selective oxidation catalyst bed packed with a selective oxidation catalyst which selectively oxidizes carbon monoxide for further reducing the concentration of carbon monoxide in the outlet gas of the shift reaction part, wherein the hydrogen production apparatus comprises an oxygen absorbent bed packed with an oxygen absorbent capable of absorbing oxygen and capable of being regenerated at 80° C. or more and 150° C. or less by a reducing gas, and the oxygen absorbent bed and the selective oxidation catalyst bed are stacked in a single reactor vessel with the oxygen absorbent bed on the downstream side with respect to the flow of the hydrogen-containing gas, the hydrogen production apparatus comprises means for opening the downstream of the oxygen absorbent bed to the atmosphere, the hydrogen production apparatus comprises a cooling system for cooling the oxygen absorbent bed to 80° C. or more and 150° C. or less; wherein the cooling system comprises a channel flowing a cooling medium through the reactor vessel holding the oxygen absorbent; and wherein the channel passes through the selective oxidation catalyst bed and the oxygen absorbent bed.
