Embodiments of a compact pressure swing reformer are disclosed. Certain embodiments have a construction comprising multiple rotating reformer beds, high temperature rotary valves at the bed ends, and E-seals to seal the beds to the valves. Several possible designs for introducing reactants into the beds also are disclosed. The multiple reformer beds are configured to provide for pressure equalization and 'steam push'. The compact pressure swing reformer is suitable for use in fuel cell vehicle applications.

Compact pressure swing reformer

Disclosed herein are embodiments of a rotary gas separation device, such as a rotary pressure swing adsorption device. The rotary pressure swing device can include, for example, a rotor with a plurality of adsorber elements, a stator with a plurality of conduits, and a rotary valve comprising a seal assembly positioned between the rotor and the stator.

Low energy, high recovery, rapid cycle kinetic PSA for biogas

Embodiments of a rapid cycle PSA apparatus are described that are useful for producing a hydrogen enriched product gas comprising not more than about 50 ppm carbon monoxide by volume and with a hydrogen gas recovery of at least about 70% by adsorptive separation from a syngas feed gas mixture comprising at least about 50 percent hydrogen and at least about 1 percent carbon monoxide by volume. One disclosed embodiment of a rapid cycle PSA apparatus comprised at least 3 adsorber elements each having at least one thin adsorbent sheet material which comprises at least one adsorbent material therein, and a bed size factor less than about 4.0 seconds. Embodiments of a rapid cycle PSA process also are described that utilize disclosed embodiments of the rapid-cycle PSA device.

Rapid cycle syngas pressure swing adsorption system

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.

Engineered adsorbent structures for kinetic separation

A method and system for adsorptive separation of a feed gas mixture provides for increased system efficiency and product recovery. The requirement for purge gas streams consuming desired product gas to regenerate adsorption beds is reduced through an inventive method for adsorbent selection and adsorption bed and process design.
