<p>PROBLEM TO BE SOLVED: To provide an apparatus for producing hydrogen, having an extremely simple equipment constitution for preheating a raw material gas and generating and superheating, etc., of process steam at a low equipment cost and apply a slight load thereto in aspects of maintenance and control over the equipment and suitable for a small capacity. SOLUTION: This apparatus for producing hydrogen is capable of reforming a desulfurized raw material hydrocarbon at a high temperature with steam in a reforming furnace 2, converting carbon monoxide in the reformed gas comprising hydrogen, the carbon monoxide, gaseous carbon dioxide, methane, etc., into hydrogen in a CO conversion column 7, then treating the prepared conversion product with a hydrogen pressure swing adsorption(PSA) device 8 and producing the high-purity hydrogen. The raw material hydrocarbon is mixed with pure water for the steam and the resultant mixture is introduced into a raw material/steam heater 1 and heated by the heat exchange with a high-temperature combustion gas emerging from the reforming furnace 2 to provide a high-temperature mixture substance of the hydrocarbon with the steam. The obtained mixture is subsequently introduced into reactional tubes 3 of the reforming furnace 2 to carry out the high-temperature steam reforming reaction.</p> |
