    摘要： A thermodynamic pressure swing adsorption cycle utilizing "loudspeaker" diaphragms or pistons which are located at the top and bottom of a column containing a bed of adsorbent. The diaphragms are vibrated out of phase with each other so as to provide a displacement wave in the gas mixture within the bed of adsorbent. In addition to this displacement wave the gas is compressed prior to upward displacement and the gas pressure is lowered before the downward displacement by way of a second set of "loudspeakers" which form the side walls of the column. The second set of loudspeakers vibrate in phase with each other and operate at the same frequency as the displacement speakers.

    摘要： A method of separating a first gaseous component from a gas mixture comprising a first gaseous component and a second gaseous component comprising passing the gaseous mixture into an adsorption zone containing an adsorbent material capable of preferentially adsorbing at least one of the gaseous components in the gaseous mixture, to separate the first gaseous component from the second gaseous component wherein the adsorbent material is a monolithic wheel having a plurality of channels throughout, the channels being aligned parallel to the direction of flow of the gaseous mixture and having a wall thickness of less than 1 mm and recovering the non-preferentially adsorbed gaseous component from the adsorption zone. Preferably, the adsorption zone comprises multiple layers of monolithic structures in the shape of a wheel stacked one upon the other in a direction parallel to the direction of the flow of the gaseous mixture and formed by spirally winding a sheet of corrugated adsorbable material about a hub.
