Abstract: A process for the separation by adsorption of at least a component of a gaseous mixture whereby the gas mixture is circulated through an adsorbent mass. A plurality of adsorbent mass compartments are provided and are arranged sectorially about and fixed to a support shaft rotating about an axis, and collection chambers are provided radially internally and externally of each adsorbent compartment. Gas circulation is provided radially through each adsorbent compartment as it rotates about a stationary gas distribution unit.

Abstract: Enclosure for separating a component from a gas mixture by adsorption, of the elongated structure type including at least one granular adsorbing product and having a device for introducing and withdrawing gas to ensure a gas circulation in longitudinal direction relative to the enclosure of the elongated structure type. The enclosure is a gas bottle with closed bottom and a cylindrical lateral wall narrowing into a neck provided with an introduction-withdrawing head having a first axial duct extending into a dipping tube reaching at a short distance from the bottle bottom and a second duct opening inside the bottle at the level of the bottle neck. Use for the separation of gas mixtures, such as for the production of hydrogen.
