Patent number: 9157357Abstract: In situations where the demand for syngas is intermittent, a fuel processor is operated to provide a high absolute hydrogen and carbon monoxide production, rather than to give a high fuel-specific hydrogen and carbon monoxide production. When a syngas generator is operated to intermittently produce syngas, a heating process can be performed between periods of syngas demand in order to keep the fuel processor within a desired temperature range. The heating process can comprise various steps or events including performing a heating event, allowing a standby period, and/or performing a carbon conversion event. Carbon formed during the process of converting fuel to syngas can be advantageously converted to maintain the temperature of the fuel processor within a desired range in between periods of syngas demand. A predictive method can be employed to control at least a portion of the heating process.Type: GrantFiled: August 19, 2011Date of Patent: October 13, 2015Assignee: WESTPORT POWER INC.Inventors: Xuantian Li, William Allison Logan, Christopher Gordon Stoner, Andre Boulet, Erik Paul Johannes, Paul Sebright Towgood, Jacobus Neels

Patent number: 9032708Abstract: In situations where the demand for syngas is prolonged, a fuel processor is operated continuously to provide a syngas stream for a prolonged period. The equivalence ratio of reactants supplied to the fuel processor is controlled so that a high fuel-conversion efficiency to hydrogen and carbon monoxide is obtained at temperatures correspondent to carbon production balance, where carbon is formed and gasified at approximately the same rate in the fuel processor.Type: GrantFiled: August 19, 2011Date of Patent: May 19, 2015Assignee: Westport Power Inc.Inventors: Xuantian Li, Andre Boutel, Jacobus Neels, William Allison Logan

Patent number: 8747496Abstract: A fuel processor for producing a hydrogen-containing product stream from a fuel stream and an oxidant stream, comprises a mixing tube from which the combined fuel and oxidant stream is directed substantially axially into a reaction chamber. The reaction chamber comprises a turn-around chamber and a turn-around wall at one end for re-directing the combined reactant stream, so that in the turn-around chamber the re-directed stream surrounds and is in contact with the combined reactant stream flowing substantially axially in the opposite direction. This design and opposing flow configuration creates a low velocity zone which stabilizes the location of a flame in the fuel processor and offers other advantages.Type: GrantFiled: April 30, 2008Date of Patent: June 10, 2014Assignee: Westport Power Inc.Inventors: Jacobus Neels, Xuantian Li, Richard Allan Sederquist, Andre Boulet, William Allison Logan
