摘要： A particulate filter is fluidly connected to and disposed downstream from a diesel engine exhaust stream outlet. The filter has a plurality of filter segments that have differing physical properties or structural characteristics such that the engine exhaust stream to fuel stream ratio is maintained substantially consistent among segments during their regeneration. A method for regenerating a segmented filter comprises maintaining the engine exhaust stream to fuel stream ratio substantially consistent among segments during their regeneration.

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： 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 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.
