Hydrogen is separated from a feed gas containing such impurities as methane, ethane, propane, nitrogen, oxygen and carbon monoxide, such as refinery tail gas or gas streams obtained e.g. by oxidising methane, by passing the feed gas by line 2 into and upward through an adsorption zone 3 in countercurrent to a downwardly moving bed of particulate adsorbent maintained by cooling coils 4 at below -50‹C. but above the temperature at which any component of the feed liquefies or solidifies. Unadsorbed purified hydrogen is removed by line 8, while loaded adsorbent is passed to rectification zone 5 (heated at 6) where impurities are desorbed and removed by line 7. Regenerated adsorbent is then passed by screw 9 into duct 10, where it is pneumatically lifted, by a bled-off fraction of the pure effluent hydrogen stream passed by line 11, to the head 1 of the column. The pressure in this recycle stream is so adjusted that a portion of the stream flows up past screw 9 and through the column, thereby acting as a purge gas and preventing contamination of the product stream. Suitable adsorbents specified are activated charcoal, natural and synthetic zeolites, sepiolite, silica, silica-alumina, and alumina.
