Abstract
Methods and systems for producing hydrogen are provided. In one embodiment, a method of producing hydrogen comprises reacting a feed source with steam to produce a gas mixture containing hydrogen and a residue gas; introducing the gas mixture into a purification unit; adsorbing the residue gas; and discharging at least a portion of the hydrogen. The method further comprises depressurizing the purification unit; discharging at least a portion of the residue gas during the depressurization; recycling the residue gas to the feed source; and discharging the residue gas remaining in the purification unit. In another embodiment, the method includes discharging a portion of the residue gas during the depressurization such that the residue gas discharged has a higher hydrocarbon content than the secondary product remaining in the purification unit.
