ABSTRACT:
An apparatus for the adsorption of molecules from a gaseous medium comprises at least two adsorption chambers for receiving an adsorbent; at least one pair of ducts forming inlets and outlets associated with each of said adsorption chambers; means for passing the gaseous medium selectively into and out of said ducts and adsorption chambers so as to form an adsorption circuit; means for passing a hot gaseous regeneration medium into and out of said ducts and adsorption chambers so as to form a regeneration circuit; valve means associated with said ducts for selectively including one or the other pair of ducts and adsorption chambers in said adsorption circuit or in said regeneration circuit, the said valve means comprising a pair of cooperating and aligned, relatively rotatable valve discs, and openings provided in said valve discs for connection with said ducts forming the adsorption and regeneration circuit, all of said openings being equidistant from the central axis of said discs and the said openings being associated in peripheral direction of the discs, alternatingly, with the ducts forming the adsorption circuit and with the ducts forming the regeneration circuit.
