Patent number: 7828877Abstract: An inventive adsorptive gas separation process is provided capable of producing a purified methane product gas as a light non-adsorbed product gas as opposed to a heavy desorbed exhaust gas component, from a feed gas mixture comprising at least methane, and carbon dioxide. In an embodiment of the invention, the feed gas mixture may comprise at least about 10% carbon dioxide, and the purified methane product gas may be desirably purified to contain less than about 5000 ppm carbon dioxide. In another embodiment of the invention, the feed gas mixture may comprise at least about 50% carbon dioxide, and the purified methane product gas may be desirably purified to contain less than about 5000 ppm carbon dioxide.Type: GrantFiled: November 7, 2005Date of Patent: November 9, 2010Assignee: Xebec Adsorption, Inc.Inventors: James A.

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.

Patent number: 5387289Abstract: A system for depositing a film on a substrate in a CVD process has a second-source injection sub-system for injecting a control gas. The deposition rate of the material deposited in the CVD process is a function of the concentration of the control gas at the point that material is deposited. The second source injection sub-system provides a concentration gradient of the control gas relative to the substrate surface coated, and alters the thickness uniformity of the film. By controlling the gradient one may control the thickness uniformity profile. In another embodiment, the invention applies to dry etching with reactive gas, and the etching rate is controlled by second source provision of a control gas.Type: GrantFiled: September 22, 1992Date of Patent: February 7, 1995Assignee: Genus, Inc.Inventors: Johannes J.
