    摘要: Ammonia in a gas stream comprising oxygen and nitrogen may be effectively completely oxidized to a mixture of NO and NO2 for further processing to nitric acid. The gas stream is flowed over fine particles of La1-xSrxCoO3 and/or La1-xSrxMnO3, and/or La1-xSrxFeO3 where x=about 0.1, 0.2, or 0.3. The particles are supported as catalyst layers on gas stream-contacting surfaces of a flow-through catalyzed oxidation reactor. These relatively inexpensive perovskite-type materials may be used to promote oxidation of ammonia at temperatures below about 450° C. to about 500° C. to selectively produce a mixture of NO and NO2. This mixture is suitable for further oxidation to NO2 for adsorption into water to make nitric acid.

    摘要: An exhaust gas aftertreatment system for treating an engine-out exhaust gas feedstream of a spark-ignition direct-injection engine includes a multi-stage catalytic converter comprising a converter inlet, a converter outlet, and a substrate having a first end associated with the converter inlet and a second end associated with the converter outlet. The substrate further includes a multiplicity of flow passages between the first and second ends of the substrate, a first surface location corresponding to the first end of the substrate, and a second surface location corresponding to the second end of the substrate. A first washcoat stage is applied to the substrate at the first surface location corresponding to the first end of the substrate. A second washcoat stage is applied to the substrate at the second surface location corresponding to the second end of the substrate. The first and second washcoat stages include washcoats formulated to generate hydrogen and ammonia from the engine-out exhaust gas feedstream. An ammonia-selective catalytic reduction device is downstream of the first and second washcoat stages.

    摘要: A method for monitoring performance of a passive selective catalytic reduction system includes operating the internal combustion engine in a preconditioning mode. Subsequent to the preconditioning, an air/fuel excursion is introduced into the exhaust gas feedstream and a signal output from a sensor monitoring the exhaust gas feedstream in the selective catalytic reduction system during the air/fuel excursion is monitored. An operating effectiveness is determined for the selective catalytic reduction system correlated to the signal output from the sensor monitoring the exhaust gas feedstream.

    摘要: A system according to the principles of the present disclosure includes a rate determination module, a storage level determination module, and an air/fuel ratio control module. The rate determination module determines an ammonia generation rate in a three-way catalyst based on a reaction efficiency and a reactant level. The storage level determination module determines an ammonia storage level in a selective catalytic reduction (SCR) catalyst positioned downstream from the three-way catalyst based on the ammonia generation rate. The air/fuel ratio control module controls an air/fuel ratio of an engine based on the ammonia storage level.
