Patent number: 7902114Abstract: 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.Type: GrantFiled: October 22, 2007Date of Patent: March 8, 2011Assignee: Xebec Adsorption Inc.Inventors: Bowie G.

Patent number: 7645324Abstract: Improved adsorbent sheet based parallel passage adsorbent structures for enhancing the kinetic selectivity of certain kinetic-controlled adsorption processes, such as PSA, TSA and PPSA processes, and combinations thereof, are provided. The enhancements in kinetic selectivity made possible through the implementation of the present inventive improved adsorbent structures may unexpectedly enable significant intensification of selected kinetic adsorption processes relative to attainable performance with conventional adsorbent materials in beaded or extruded form. Such process intensification enabled by the present inventive adsorbent structures may provide for increased adsorption cycle frequencies, and increased gas flow velocities within the adsorbent beds, which may increase the productivity and/or recovery of a kinetic adsorption system incorporating the inventive adsorbent structures.Type: GrantFiled: January 6, 2006Date of Patent: January 12, 2010Assignee: Xebec Adsorption Inc.Inventors: Edward J. Rode, Andre J. J. Boulet, Aaron M. Pelman, Matthew L. Babicki, Bowie G. Keefer, James A. Sawada, Soheil Alizadeh-Khiavi, Surajit Roy, Andrea C. Gibbs, Steven M. Kuznicki

Publication number: 20090214902Abstract: Disclosed embodiments concern adsorptive gas bulk separation systems and methods that may be advantageously less expensive to utilize than some in the prior art. Embodiments of the present invention concern processing a feed gas source, typically comprising at least one fuel gas component and at least one diluent, using a displacement purge adsorptive separator apparatus comprising at least one adsorbent bed, at least one purge gas source for purge regeneration of the at least one adsorbent bed, and a product conduit for supplying upgraded gas product. The feed gas typically is supplied to the displacement purge adsorptive separator apparatus at substantially the ambient pressure of the feed gas source. The displacement purge adsorptive separator apparatus is operable to adsorb at least a portion of the at least one diluent component from the feed gas stream to produce an upgraded gas.Type: ApplicationFiled: June 15, 2006Publication date: August 27, 2009Inventors: Aaron M. Pelman, Surajit Roy, Sean Patrick Mezei

Patent number: 6902602Abstract: The present disclosure relates to systems and processes for adsorptive gas separations where a first gas mixture including components A and B is to be separated so that a first product of the separation is enriched in component A, while component B is mixed with a third gas component C contained in a displacement purge stream to form a second gas mixture including components B and C, and with provision to prevent cross contamination of component C into the first product containing component A, or of component A into the second gas mixture containing component C. The invention may be applied to hydrogen (component A) enrichment from syngas mixtures, where dilute carbon dioxide (component B) is to be rejected such as directly to the atmosphere, and with preferably nitrogen-enriched air as the displacement purge stream containing residual oxygen (component C).Type: GrantFiled: March 14, 2003Date of Patent: June 7, 2005Assignee: QuestAir Technologies Inc.Inventors: Bowie G. Keefer, Matthew L. Babicki, Andre Jason Joseph Boulet, Aaron M. Pelman, Brian G. Sellars, Surajit Roy
