摘要： One aspect of the invention relates to a device for storing ammonia for use in SCR on board a vehicle. The device comprises an adsorption bed with a high capacity for storing ammonia. The device can be designed to hold a long-lasting charge of ammonia comparable to a urea tank, but will not release substantial amounts of ammonia into the environment even if the device is accidentally ruptured. In one embodiment, the devices are charged at stationary locations. In another embodiment, the devices are charged by vehicle-mounted ammonia synthesis plants. The device facilitate the use of small ammonia synthesis plants that operate at low pressures and give low conversions. Preferably, the devices are operated through temperature swing adsorption.

摘要： The invention relates to systems for removing NOx from exhaust. In one aspect of the invention, after adsorption, an NOx adsorber is isolated from the main exhaust flow and desorption induced by raising the temperature. The desorbed NOx is combined with a reductant and reduced over a catalyst. Preferably, the reductant is syn gas produced in an on-board reformer. The catalyst need never be exposed to the main exhaust flow, which is particularly advantageous for catalysts sensitive to water, oxygen, or sulfur. In another aspect of the invention, a recirculating flow is induced through an NOx adsorber during a regeneration cycle. Recirculation can induce greater desorption at a given temperature, provide a source of heat for the adsorber, and allow a higher conversion rate with a fixed amount of catalyst. A further aspect of the invention relates to a vehicle-mounted adsorbers with provisions for heating.

摘要： One aspect of the invention relates to a process for synthesizing ammonia from hydrogen and nitrogen in which an adsorbant is provided to adsorb ammonia as it is being produced. Adsorption of the product drives the ammonia synthesis reaction and allows the process to be carried out at pressures where the gas phase equilibrium conversion is too low for a conventional system to be practical. The invention is applicable to both small and large scale ammonia synthesis. A small scale ammonia synthesis plant can be a stationary or vehicle-mounted plant used to supply reducing agent for selective catalytic reduction of NOx in diesel exhaust. Ammonia can be desorbed from the adsorbant, extracted from the adsorbant, or stored and transported in its adsorbed state.

摘要： One concept of the inventors relates to a system and method in which a particulate filter comprises at least about 40% by weight of an NOx adsorbant. The filter can be used as both an NOx trap and a particulate filter. By constructing the filter elements using a substantial amount of NOx adsorbant, a large volume of NOx adsorbant can be incorporated into the particulate filter, which substantially reduces the volume and expense of an exhaust system that includes both a catalytic diesel particulate filter and an NOx trap having a large quantity of NOx adsorbant. In a preferred embodiment, the filter also oxidizes NO to NO2. In another preferred embodiment, an SCR catalyst is position downstream of the filter elements.

摘要： The invention relates to a fluid power accumulator in which the fluid undergoes a state change as the system is pressurized to store energy. A state change can be a phase change, a chemical reaction, or a combination of these. Generally the state change results from the interaction of a compressible fluid contained in the accumulator with another substance, which can be a fluid or a solid. Preferably, the state change includes the physical adsorption of a fluid by a solid adsorbant. The invention can improve the energy storage density of a fluid power accumulator, allow a given energy storage density to be achieved at a lower maximum pressure, facilitate heat transfer and storage within an accumulator, and/or improve accumulator efficiency by storing energy in a form other than thermal energy, such as in the form of chemical energy.

摘要： The invention relates to systems and methods for treating oxygen-rich NOx-containing exhaust. The systems and methods comprise using first and second NOx reducing catalysts. According to one aspect of the invention, the first catalyst reduces NOx in oxygen-rich exhaust primarily through reaction with a first reductant species and the second catalyst reduces NOx in oxygen-rich exhaust primarily through reaction with a second reductant species. Collectively, the two catalysts are substantially more effective than either of the catalysts individually in reducing the concentration of NOx in the exhaust. According to another aspect of the invention, an exhaust system is configured to inject a first reductant species primarily at a first location upstream of the first NOx reducing catalyst, and is configured to inject a second reductant species primarily at a second location downstream of the first NOx reducing catalyst, but upstream of the second NOx reducing catalyst.

摘要： One aspect of the invention relates to a NOx trapping device for a vehicle exhaust system having a plurality of NOx adsorbers. The device has a mobile framework configured to hold the NOx adsorbers and move them in sequence through a plurality of positions. A manifold channels exhaust to one or more of the NOx adsorber positions. The mobile framework is adapted to move the NOx adsorbers in and out of position to receive the exhaust. The adsorbers can be regenerated while they are not receiving any exhaust. The invention facilitates the use of multiple NOx adsorbers in an exhaust system, particularly the use of more than two adsorbers. The invention avoids complex exhaust valving, which is normally associated with multiple adsorber systems. In one embodiment, treated exhaust and exhaust from an adsorber undergoing regeneration are combined and supplied to an SCR reactor or an oxidation catalyst.
