摘要： Described here are systems and methods for treating fuel injected exhaust streams. In general, the systems comprise a fuel injector, a pre-combustor, and a fuel combustor. The methods described herein include methods for regenerating a NO x trap or a DPF, and methods for generating a substantially uniform fuel air mixture at a fuel combustor inlet, or a substantially uniform temperature at a fuel combustor outlet. The methods of regenerating a NO x trap typically comprise the steps of injecting fuel into an exhaust stream, passing the stream through a pre-combustor, operating the pre-combustor to at least partially combust the injected fuel, reacting the fuel and exhaust stream mixture within a fuel combustor to generate a reducing gas mixture, and introducing the reducing gas mixture into a NO x trap, whereby the NO x trap is regenerated. Similar methods for regenerating a diesel particulate filter are also described. Control strategies are also provided.

摘要： The present invention provides systems and methods to improve the performance and emission control of internal combustion engines equipped with nitrogen oxides storage-reduction (“NSR”) emission control systems. The system comprises a NSR catalyst (206), a fuel processor (200) located upstream o the NSR catalyst, and at least one fuel injection port (208). The fuel processor (200) converts a fuel into a reducing gas mixture comprising CO and H 2. The reducing gas mixture is then fed into the NSR catalyst (206), where it regenerates the NSR adsorbent, reduces the NO x to nitrogen, and optionally periodically desulfates the NSR catalyst. The fuel processor (200) comprises one or more catalysts (308), which facilitate reactions such as combustion, partial oxidation, and/or reforming and help consume excess oxygen present in an engine exhaust stream. The methods of the present invention provide for NSR catalyst adsorbent regeneration using pulsed fuel flow. Control strategies are also provided.

摘要： Method and apparatus for control of Zeldovich (thermal) NOx production in catalytic combustion systems during combustion of liquid or gaseous fuels in the post catalytic sections (14) of gas-turbine combustors by reducing combustion residence time in the Homogeneous Combustion (HC) zone through control of the HC Wave position, principally by adjusting the catalyst (13) inlet temperature. As the fuel/air mixture inlet temperature to the catalyst is reduced, the HC Wave moves downstream, extends the ignition delay, shortens the residence time at high temperature, thereby reducing the thermal Nox production. The countervailing increase in CO production by longer ignition delay can be limited by actively positioning the HC Wave so that thermal Nox is reduced while power output and low CO is maintained. Nox is reduced to on the order of

摘要： The invention provides methods and systems for catalytic reforming of a hydrocarbon fuel to produce hydrogen, which may be used as a power source for a fuel cell. In some embodiments, hydrogen is produced by partial oxidation or autothermal reforming of fuel in an oxygen containing gas stream that is rich the majority of the time, with periodic conversion to a lean gas stream for short periods of time to maintain catalytic activity. In one embodiment, hydrogen peroxide is used as the oxidant in an autothermal reforming process. In some embodiments, hydrogen is produced by steam reforming at a low steam to carbon ratio, with a periodic increase in the steam to carbon ratio for short periods of time to maintain catalytic activity.
