<p>PURPOSE:To contrive to improve the gas separation capacity and gas purity, by exchanging the heat of a regenerated gas with waste gas using a heater provided in the course of a regenerated gas conduit and completing the regeneration of adsorption columns of a gas separator. CONSTITUTION:A raw material methanol 1 and pure water 2 are heated in a preheater 3 and fed to a reactor 7. A heating medium heated in a heating furnace 16 is fed to the reactor 7 to heat a catalyst layer in the reactor 7. The methanol 1, etc., are passed through the catalyst layer and decomposed. The resultant decomposed gas 11 is fed to a separation unit 13 to separate hydrogen and/or carbon monoxide. In the process, a purified hydrogen conduit 14 for purified hydrogen discharged from the adsorption column 22 in the pressurized adsorption step is connected to the adsorption column 22 in the decompressed desorption step with a regenerated gas conduit 27 to carry out the heat exchange of the waste gas from the heating furnace 16 with the regenerated gas in a regenerated gas heater 25.</p> |
