Abstract (en)
[origin: WO0204096A1] The invention concerns a method for purifying PSA-type gaseous hydrogen polluted with CO and N2 which consists in passing the gas stream through an adsorption zone comprising at least an adsorbent based on 5A-zeolite and an adsorbent based on a calcium-exchanged X-zeolite. Said method is particularly efficient in terms of productivity and yield in purified hydrogen at moderate production price.
