Abstract
A hydrogen production system (X1) according to the present invention includes a reforming apparatus (Y1) having a vaporizer (1) and a reforming reactor (2), and a PSA apparatus (5). In the vaporizer (1) a mixed material (hydrocarbon-based material, water, and oxygen) is heated and vaporized. In the reforming reactor (2), steam reforming reaction and partial oxidation reaction of the hydrocarbon-based material take place at a time, so that reformed gas (containing hydrogen) is led out from the vaporized mixed material. In the PSA apparatus (5), the reformed gas is introduced into an adsorption tower loaded with an adsorbing agent, so that an unnecessary component in the gas is adsorbed by the adsorbing agent and hence hydrogen-rich gas is led out of the tower, while the unnecessary component is desorbed from the adsorbing agent, so that hydrogen-containing desorbed gas that contains the unnecessary component and hydrogen remaining in the tower is discharged out of the tower. The desorbed gas is burnt in the vaporizer (1), and combustion gas generated by burning the desorbed gas is utilized as a heat source to heat the mixed material.
