    摘要: The present invention provides a method and apparatus for heating a catalytic converter at least to a light off temperature. In accordance with the invention, the catalytic converter may be heated using a novel monolith construction, electrical heating, catalytic combination of a fuel and oxygen or combinations of these methods. Heating or thermally conditioning a catalyst in accordance with the invention rapidly brings the catalyst up to the light off temperature for the efficient conversion of pollutant gases, such as unacceptable emissions emanating from an internal combustion engine, into water, carbon dioxide and other acceptable emissions. In particular, the invention provides efficient heating of the catalytic converter despite the potential presence of water on the catalyst during startup.

    摘要: A method for the anodic electrochemical synthesis of ammonia gas. The method comprises providing an electrolyte between an anode and a cathode, providing nitrogen and hydrogen gases to the cathode, oxidizing negatively charged nitrogen-containing species and negatively charged hydrogen-containing species present in the electrolyte at the anode to form adsorbed nitrogen species and adsorbed hydrogen species, respectively, and reacting the adsorbed nitrogen species with the adsorbed hydrogen species to form ammonia. Nitrogen and hydrogen gases may be provided through a porous cathode substrate. The negatively charged nitrogen-containing species in the electrolyte may be produced by reducing nitrogen gas at the cathode and/or by supplying a nitrogen-containing salt, such as lithium nitride, into the molten salt electrolyte. Similarly, the negatively charged hydrogen-containing species in the electrolyte may be produced by reducing hydrogen gas at the cathode and/or by supplying a hydrogen-containing salt, such as lithium hydride, into the molten salt electrolyte.

    摘要: The present invention provides a self-replenishing liquid water source onboard an automobile for supplying liquid water to an electrolyzer, such as an on-board hydrogen generator useful for the suppression of unwanted emissions. While automobiles typically have water reservoirs resupplied by a person, the invention provides a passive means of water collection for reliable replenishment due to operations of the automobile itself. The invention provides condensate from the engine exhaust gas by cooling a region of the exhaust system using cooling fluid from the engine coolant system. The cooling fluid is circulated during a period following the engine cold start event when the heat load on the engine coolant system is low.
