    摘要： Chemical microreactors for chemical systhesis and their methods of manufacture are known, but have disadvantages such as extremely high manufacturing costs or poor flexibility for adaptation to various cases of application. These disadvantages are avoided by means of the microreactors and manufacturing methods according to the invention. The microreactors are characterized in that the reactors contain fluid ducts in at least one plane as well as feed and return lines for fluids, wherein the fluid ducts are defined by side walls of metal opposing each other and further side walls of metal or plastic extending between said side walls, and in which the planes are connected together and/or with a closure segment closing open fluid ducts by means of appropriate solder or adhesive layers. The manufacturing method is characterized by process sequences in which the individual reactor planes produced by means of electrolytic methods, are connected together by soldering or gluing.

    摘要： The invention relates to a procedure for controlling the reducing agent in an exhaust gas post-processing system of a combustion machine with an exhaust gas duct, in which an SCR catalytic converter is provided in the direction of flow of the exhaust, wherein a reducing agent generation system has an NOx and CO/H2 generation unit,, an oxidation catalytic converter and a combined NOx storage / ammonia generation unit in the standard gas route of the reducing agent generation system, and, in order to reduce nitrogen oxide, ammonia is added as a reducing agent in front of the SCR catalytic converter by the reducing agent generation system, wherein source materials for the generation of ammonia are at least intermittently added to the NOx and CO/H2 generation unit via a fuel supply line and via an air supply line, wherein during the fat phase the air/fuel composition is changed in front of the oxidation catalytic converter in the form of a lambda modulation for a lambda value. It can thus be achieved that, in pulse mode, a high H2/CO yield can be achieved with a simultaneously low HC slip and the higher HC penetrations associated with the natural aging of the catalytic converter and the decreasing H2/CO yields are compensated. Influences resulting from the reactor geometry of the oxidation catalytic converter can be influences or compensated with the procedure in terms of its drive-away characteristic.

    摘要： A method for metering ammonia into the exhaust-gas region of an internal combustion engine and a device for implementing the method. The ammonia storage capacity of an SCR catalytic converter situated in the exhaust-gas region of the internal combustion engine is utilized. After the internal combustion engine has been switched off, ammonia is introduced into the exhaust-gas region in front of the SCR catalytic converter. Thus, following a renewed start-up of the internal combustion engine, the ammonia required in the SCR catalytic converter for reducing the nitrogen oxides contained in the exhaust gas of the internal combustion engine are already available before an ammonia source is ready for operation. The procedure eliminates the need for a pressure storage of ammonia in the switched-off state of the internal combustion engine.

    摘要： The invention concerns a device to produce ammonia as a reducing agent for the selective catalytic reduction (SCR) of nitrogen oxides in the exhaust gas of a combustion source, especially of an internal combustion engine, whereby the ammonia is admixed with the exhaust gas in the direction of flow in front of a SCR-catalytic converter. In so doing, provision is made for a nitrogen oxide production unit separated from the combustion source and its exhaust gas duct and a hydrogen production unit separated from the combustion source and its exhaust gas duct; and nitrogen oxide of the nitrogen oxide production unit and the hydrogen of the hydrogen production unit are delivered at least to a storage catalytic converter or a nitrogen oxide storage and a subsequently connected catalytic converter for the storage of the nitrogen oxide and for the formation of ammonia. The invention concerns additionally a procedure for the production of ammonia as a reducing agent for the selective catalytic reduction (SCR) of nitrogen oxides in the exhaust gas of a combustion source, especially of an internal combustion engine, whereby the ammonia is admixed with the exhaust gas in the direction of flow in front of a SCR-catalytic converter. In so doing, nitrogen oxide is produced in a nitrogen oxide production unit separate from the combustion source an its exhaust gas duct and is stored in at least one storage catalytic converter or a nitrogen oxide storage and a subsequently connected catalytic converter. Furthermore, hydrogen and/or a hydrogen-carbon monoxide-mixture is produced in a hydrogen production unit separated from the combustion source and its exhaust gas duct and delivered to a storage catalytic converter. Hydrogen and the stored nitrogen oxide are converted catalytically to ammonia in the storage catalytic converter or in the catalytic converter. Device and procedure allow for a self-sufficient production of ammonia outside of the exhaust gas tract of the combustion source and without an intervention into the operating parameters of the combustion source, whereby operating resources normally transported exclusively in a motor vehicle are used.

    摘要： The invention concerns a device for the production of ammonia for the selective catalytic reduction of nitrogen oxides in the exhaust of an internal combustion engine with an air supply. If the air supply includes a power supply, which is independent of the power of the internal combustion engine, and which powers a compression stage for air supply, the result would be an efficient production of reduction agents even under varying operating conditions of the internal combustion engine and the addition of the reduction agent in proper amounts to the exhaust to be cleaned.
