An apparatus for separating or purifying gaseous material having more or less adsorbable components includes a high pressure inlet chamber, a high pressure outlet chamber and a low pressure chamber. Adsorbent means retain an adsorbent capable of selectively adsorbing the more adsorbable component at a predetermined pressure level. There are also means for establishing a high pressure flow path for the gaseous material from the high pressure inlet chamber through the adsorbent means to the high pressure outlet chamber. The more adsorbable component is adsorbable by the adsorbent in the high pressure flow path. Further means establish a low pressure desorption flow path from the adsorbent means to the low pressure chamber. The two means for establishing flow paths are operable simultaneously to continuously separate or purify the gaseous material. A process for separating or purifying gaseous material is also disclosed. The gaseous material is pressurized to a pressure at which the more adsorbable component will be adsorbed by an adsorbent preferentially compared the less adsorbable component. The pressurized gaseous material is caused to flow through and contact the adsorbent to adsorb the more adsorbable component, thereby separating the more adsorbable component from the less adsorbable component.

A pressure swing adsorption process for separating or purifying a gas mixture having more and less adsorbable components selectively adsorbable at predetermined pressure levels comprising continuously and simultaneously subjecting a rotating bed of adsorbent material to the following steps by rotating the bed to sequentially align discrete adjacent sections of the bed with a plurality of sectors within a single vessel: (a) sequentially aligning each section of the bed with a first sector of the vessel in which pressurized gas mixture flows through the section of the bed aligned with the first sector and contacts the adsorbent to adsorb the more adsorbable component, thereby separating the more adsorbable component from the less adsorbable component; (b) recovering the unadsorbed less adsorbable component as a primary product; (c) subsequently sequentially aligning each section with a second sector of the vessel in which the pressure is lowered to desorb from the section of the bed aligned with the second sector the adsorbed more adsorbable component and any adsorbed portion of the less adsorbable component; and (d) recovering the desorbed components as a secondary product.
