A Temperature Swing Adsorption method for separating a first component, comprising a more adsorbable component, from a feed stream comprising more than 50 mol % of a second component, comprising a less adsorbable component, is provided. The method includes providing an adsorbent structure suitable for adsorbing the first component, the structure being of the parallel passage contactor type, and cyclically implementing the following steps. Passing the feed stream through the adsorbent structure thus adsorbing the first component and producing a stream depleted in the first component and enriched in the second component. Heating the adsorbent structure to desorb the adsorbed first component by means of circulating a heating stream enriched in the first component at a temperature suitable for regeneration. And cooling the structure by means of passing through it more than 50% of the stream enriched in the second component produced in the step a).

A gas separation membrane module is formed from a woven fabric of weft membrane hollow fibers and warp yarns. The membrane module includes an active hollow fiber region spanning the inner edges of the two tubesheets. The membrane module also includes two tubesheets formed by encapsulating membrane fiber on one or both ends. The tubesheet on the end includes a first sub-region adjacent the active fiber and a second sub-region extending from first sub-region to the outer face of the tubesheet. The spacing of the warp threads is relatively denser in the first sub-region than in the active region or the second sub-region.

A container for storing compressed gas includes a plurality of aligned glass capillaries extending into a tubesheet. Each of the capillaries has an open end flush with a front face of the tubesheet. An end cap having a gas outlet connectable to a compressed gas valve or conduit is fitted to the tubesheet in gas-tight fashion to form a high pressure space defined by inner surfaces of the capillaries, the front face of the tubesheet, and inner surfaces of the end cap.

A dense hydrogen-permeable layer, such as palladium or palladium alloy, is deposited on a porous hollow fiber. A porous hollow fiber is defined as having an inner diameter of approximately 30 microns to approximately 1500 microns and an outer diameter of approximately 100 microns to approximately 2000 microns. This allows an order-of-magnitude increase in the surface per volume ratio in a hydrogen separation or purification module, or a membrane reformer or reactor.
