Abstract
A continuous process for separating hydrogen in high purity from a gaseous hydrogen-containing mixture by absorbing in an absorber unit the hydrogen by metal hydride forming particles suspended in an inert liqid and desorbing in a desorber unit the hydrogen from the hydrided particles includes the step of treating the suspension of the hydrided particles before entering the desorber unit to remove dissolved gaseous non-hydrogen components by stripping with hydrogen, preferably with a part of desorbed hydrogen. By this way it is possible to obtain hydrogen having a purity of more than 99.9%.
