High-pressure steam supply in hydrogen production process is made more efficient by water gas shift process which comprises, in alternating sequence: (a) a reaction stage wherein a feed gas comprising CO and H2O is fed into a water gas shift reactor containing a sorbent material capable of adsorbing H2O and CO2 and wherein a product gas issuing from the reactor is collected, (b) a regeneration stage wherein CO2 is removed from the reactor, (c) a loading stage, wherein H2O is fed into the reactor; wherein said feed gas mixture has a molar ratio of H2O to CO below 1.2, and the loading stage is performed at a lower pressure than the pressure of the reaction stage. |
