Patent number: 9687803Abstract: 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.Type: GrantFiled: September 28, 2012Date of Patent: June 27, 2017Assignee: Air Products and Chemicals, Inc.Inventors: Soheil Alizadeh-Khiavi, Brooke Cox, Kamal Hatami, Daryl Musselman, Rajeev Agnihotri, Paul Berlowitz, Bruce Derites, Jeffrey Frederick, Jeffrey Grenda, Frank Hershkowitz, Zhiguo Hou, Novica Rados, John Siller, Richard Socha, George Walchuk

Patent number: 8858689Abstract: A gas separation device is disclosed. In particular, seal assemblies and adsorbent element constructions for a gas separation device such as a pressure swing adsorption device are disclosed. The seal assembly can be part of a rotary valve and can include a seal backer and a floating seal positioned within a bore in the seal backer. The floating seal is configured to press towards and seal against an adjacent rotor. Valve action is provided as apertures in the floating seal and rotor are brought into and then out of alignment as a result of relative rotation therebetween. The seal assembly can include two types of gas chambers to apply balanced sealing pressures over the sealing surface of the valve, one type configured to receive pressurized process gas from within the device and the other configured to receive gas from an independently controlled pressurized gas source.Type: GrantFiled: July 26, 2012Date of Patent: October 14, 2014Assignee: Air Products and Chemicals, Inc.Inventors: Christopher Stoner, Christopher R. McLean, Daryl Musselman
