摘要： A diesel particle filter which comprises a ceramic wall flow filter substrate and two coatings is described. The first coating which is applied in the inflow channels and is composed of high-melting materials has such a nature that it closes the inflow channels and pores in the wall connecting the inflow channels and outflow channels to soot particles on the inflow side without preventing passage of the gaseous exhaust gas constituents. The second coating is introduced into the wall between inflow channels and outflow channels and is of such a nature that it can effectively catalyze the selective reduction of nitrogen oxides by means of a reducing agent. The resulting component is an SCR-catalytically active particle filter and displays excellent banking-up pressure properties combined with high filtration efficiency and good regeneration properties. Furthermore, the component displays good aging stability of the NOx conversion activity.

摘要： An SCR-catalytically active diesel particle filter having a ceramic wall flow filter substrate with inflow channels, outflow channels, walls separating the inflow and outflow channels, and two coatings. The first coating is applied in inflow channels, is composed of high-melting point materials, and closes the inflow sides of pores in walls connecting the inflow channels and outflow channels to soot particles without preventing passage of gaseous exhaust gas constituents. The second coating is within the walls between inflow channels and outflow channels, and effectively catalyzes the selective reduction of nitrogen oxides when in the presence of a reducing agent. The particle filter displays excellent banking-up pressure properties combined with high filtration efficiency and good regeneration properties; and displays good aging stability of NOx conversion activity.

摘要： To equip a diesel particle filter with a zeolite-containing coating uniformly over the entire length of the particle filter and with a further zeolite-free coating which is applied, from the entry side of the filter, solely up to a specific length of the filter, it is proposed, first, to apply the zeolite-free coating from the entry side of the filter and only thereafter to apply the zeolite-containing coating over the entire length of the filter from the exit side of the filter. As a result of this sequence of coatings, a better adhesive strength of the coatings than when both coatings are applied from the entry side is ensured.

摘要： The present invention describes an exhaust-gas purification system for an internal combustion engine made of an oxidation catalyst arranged close to the engine, a subsequent hydrocarbon adsorber and a particulate filter arranged downstream thereof and provided with another oxidation catalyst. The oxidation catalyst ensures that emission limits with respect to carbon monoxide and hydrocarbons are satisfied in normal driving mode. During operating states with exhaust-gas temperatures below about 200° C., the oxidation catalyst can no longer oxidize carbon monoxide and hydrocarbons. Instead, the hydrocarbons are adsorbed by the hydrocarbon adsorber during these operating phases. In order to initiate the periodical regeneration of the particulate filter, the exhaustgas temperature of the internal combustion engine is raised by engine modifications. The increased exhaust-gas temperature leads to desorption of the previously stored hydrocarbons, which are then burned at the oxidation catalyst of the particulate filter, thereby supporting the regeneration of the particulate filter.
摘要翻译：本发明描述了一种由靠近发动机设置的氧化催化剂制成的内燃机排气净化系统，后续的烃吸附器和布置在其下游并具有另一氧化催化剂的颗粒过滤器。氧化催化剂确保在正常驾驶模式下满足一氧化碳和碳氢化合物的排放限制。在废气温度低于约200℃的运行状态下，氧化催化剂不再能够氧化一氧化碳和碳氢化合物。相反，烃在这些操作阶段被烃吸附器吸附。为了开始颗粒过滤器的定期再生，通过发动机改造来提高内燃机的废气温度。增加的废气温度导致先前储存的烃的解吸，然后在颗粒过滤器的氧化催化剂上燃烧，从而支持颗粒过滤器的再生。

摘要： Methods and apparatus, including computer program products, for generic archiving of enterprise service oriented architecture data. In general, an identification of an instance of a business object to archive is received. Information defining the business object is retrieved. A schema for the type definition and a definition of the instances of the business object in accordance with the schema is generated. The schema may be in accordance with a platform-independent file format including information reflecting the hierarchy of the business object. The schema may include hierarchy levels that reflect each hierarchy level of the business object. Each hierarchy level, with the exception of hierarchy levels including references to stand-alone business objects, may have the respective attributes of the hierarchy level of the business object. Instance data may be generated to reflect the instance of the business object, the instance data being in accordance with the schema.

摘要： The invention relates to a process for coating ceramic honeycomb bodies with a coating suspension containing, in a carrier liquid, catalyst components as solids and/or in dissolved form. The honeycomb bodies have parallel flow channels running through them. The walls of the flow channels generally have an open pore structure. To coat the channel walls and in particular also the interior surfaces of the pores with the coating suspension, it is proposed that the flow channels be temporarily alternately closed and the coating suspension be forced through the open pore structure of the channel walls. The coating is subsequently dried and calcined. To close the flow channels, it is possible to use thermally or chemically decomposable or soluble compositions which are decomposed or dissolved either during calcination or by means of a subsequent chemical treatment. The coated honeycomb bodies are preferably used for the purification of exhaust gases from automobiles.

摘要： Coating a wall-flow filter with a catalytically active coating generally increases the exhaust-gas backpressure in the filter. The increase in the exhaust-gas backpressure is particularly pronounced if a slurry of fine-particle catalyst materials is used for the coating operation. The increase in the exhaust-gas backpressure can be restricted to a tolerable level if, prior to the coating operation, the slurry is so finely milled that virtually the entire mass of the catalyst materials is introduced into the pores of the filter and deposited on the inner surfaces of the pores. This is the case if the d90 diameter of the particles in the slurry is reduced to below 5 μm by milling.

摘要： The invention relates to particle filters having an open pore structure for separating particles from fluids, which, for modification of their properties or for treatment of the fluid to be filtered, are provided with additional metal oxides or mixed metal oxides and optionally with further catalytically active components. In particular, the invention relates to particle filters treated with a catalytically active material, which is used for the treatment of the waste gases from combustion processes, in particular for the treatment of the exhaust gases of internal combustion engines. By impregnation of the filter bodies in a solution of a metal oxide sol or a mixed metal oxide sol, the preformed sol particles are deposited on the pore surfaces. Consequently, catalytic activations of the filter with good temperature stability in combination with a moderate increase in the exhaust gas back-pressure are possible.

摘要： A process for reducing the nitrogen oxides present in a lean exhaust gas from an internal combustion engine by selective catalytic reduction on a reduction catalyst using ammonia, wherein a fraction of the nitrogen monoxide present in the exhaust gas is oxidized to nitrogen dioxide before the exhaust gas, together with ammonia, is passed over the reduction catalyst. The reduction catalyst contains a zeolite exchanged with transition metals and oxidation of the nitrogen monoxide is performed in such a way that the exhaust gas contains 30 to 70 vol. % of nitrogen dioxide before contact with the reduction catalyst.
