Using zeolites as the active adsorbent, adsorbent laminates have been fabricated with various sheet supports. These adsorbent laminates have been successfully operated for oxygen enrichment at high PSA cycle frequencies, such as upwards of at least 150 cycles per minute. Methods for making suitable adsorbent laminates are described. The methods generally involve forming a slurry comprising a liquid suspending agent, an adsorbent and a binder. Laminates are made by applying the slurry to support material or admixing support material with the slurry. The slurry can be applied to support material using a variety of techniques, including roll coaters, split roll coaters, electrophoretic deposition, etc. One method for making laminates by mixing support material with the adsorbent slurry comprises depositing the slurry onto a foraminous wire, draining the slurry material, and pressing the material to form a ceramic adsorbent paper. Spacers can be formed on adsorbent laminates to space one laminate from another. The spacer dimensions can be uniform, or can vary along a laminate, such as increasing in height from a first end to a second end of the laminate. Gas flow-through apertures also can be formed on laminates. The laminates are adjacent one another to define flow channel between adjacent bodies, whereby a portion of a gas flowing through the flow channels flows through the apertures to facilitate pressure equalization in the adsorbent structure.

Methods for their manufacture of adsorbent

An electrical current generating system is disclosed that includes a fuel cell operating at a temperature of at least about 250&#xb0; C. (for example, a molten carbonate fuel cell or a solid oxide fuel cell), a hydrogen gas separation system or oxygen gas delivery system that includes a compressor or pump, and a drive system for the compressor or pump that includes means for recovering energy from at least one of the hydrogen gas separation system, oxygen gas delivery system, or heat of the fuel cell. The drive system could be a gas turbine system. The hydrogen gas separation system or the oxygen gas delivery system may include a pressure swing adsorption module.

Energy efficient gas separation for fuel cells

A compact and efficient rotary pressure swing adsorption (PSA) apparatus with laminated sheet adsorbers is used to supply enriched oxygen and/or nitrogen streams to an internal combustion engine, allowing for reduced noxious emissions and enhanced engine performance.
