摘要： Fuel processors include at least one of a fuel introduction tube, a critical flow venturi and/or a heat exchanger along with other components. Such fuel processors are particularly suitable for use in engine system applications where a liquid fuel is introduced into an oxidant stream comprising hot engine exhaust gas, for downstream conversion in the fuel processor to produce a hydrogen-containing gas stream, such as a syngas stream.

摘要： 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.

摘要： A method of operating a syngas generator within a desired temperature range, despite a need for intermittent syngas output, involves switching between operating the syngas generator in a rich mode and a lean mode. Operation of the syngas generator in both the rich mode and the lean mode sustains the operating temperature of the syngas generator within that desired temperature range, particularly for non-catalytic reactors. The method of switching from the lean mode to the rich mode of operation can include decreasing the oxygen-to-carbon ratio of reactants supplied to the syngas generator. The flow rate of one or more of the reactant streams supplied to the syngas generator can be actively controlled in order to switch operation of the syngas generator between the rich and lean modes.

摘要： 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.

摘要： 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.

摘要： A system and method for regenerating a device in an engine exhaust after-treatment system is provided. To regenerate the device, a syngas stream is introduced into the engine exhaust stream and combusts in the presence of a catalyst in the after-treatment system, raising the temperature. A supplemental liquid fuel stream is then selectively introduced into and is vaporized by the syngas stream to form a combined fuel stream. Combustion of the combined fuel stream with the engine exhaust in the presence of the catalyst further heats the device bringing it to a temperature suitable for regeneration. The catalyst can be upstream of or within the device being regenerated.
