Description
Die Erfindung betrifft einen Kupferoxide zur Umwandlung von Ozon oder eine Mischung aus Kupferoxiden und Manganoxiden zur Umwandlung von Kohlenmonoxid enthaltenden Katalysator.The invention relates to a copper oxide for the conversion of ozone or a mixture of copper oxides and manganese oxides for the conversion of Carbon monoxide containing catalyst.
Verbrennungsmotoren, besonders in Kraftfahrzeugen, produzieren große Mengen von Stickoxiden, Kohlenmonoxid und Kohlenwasserstoffen. Bei Sonneneinstrahlung wandelt UV-Licht Stickoxide in Ozon umProduce internal combustion engines, especially in motor vehicles large amounts of nitrogen oxides, carbon monoxide and hydrocarbons. When exposed to sunlight, UV light converts nitrogen oxides into ozone
Ein kleiner Teil des Ozons reagiert mit den Kohlenwasserstoffen zu Peroxiden und freien Radikalen. Die Peroxide und freien Radikale reagieren mit NO zu mehr NO₂, welches wieder photolysiert und mehr Ozon ergibt. Bis jetzt in Kraftfahrzeuge eingebaute Edelmetall-Dreiwegekatalysatoren können 80 bis 90% der Schadstoffe umwandeln. Es gibt aber viele Kraftfahrzeuge oder Motoren, bei denen keine Katalysatoren vorhanden sind oder Katalysatoren vorhanden sind, die bereits vergiftet sind und somit nicht mehr funktionieren. Diese riesigen Mengen von Schadstoffen, die in der Luft sind, müssen entgiftet oder entfernt werden.A small part of the ozone reacts with the hydrocarbons to peroxides and free radicals. The peroxides and free radicals react with NO to more NO₂, which again photolyzes and more Gives ozone. Precious metal three-way catalysts installed in motor vehicles so far can convert 80 to 90% of pollutants. But there are many motor vehicles or engines in which there are no catalysts or there are catalysts that already exist are poisoned and therefore no longer work. These huge ones Amounts of pollutants that are in the air must be detoxified or be removed.
Ozon muß beispielsweise umgewandelt werden zu harmlosen Sauerstoff, womit die Kette der Photooxydation unterbrochen wird. Kohlenmonoxid als stark giftiges Gas (auch bei niedriger Konzentration) muß zum ungiftigen Kohlendioxid umgewandelt werden. Diese in der Luft enthaltenen Schadstoffe werden bis jetzt teilweise nicht entfernt oder umgewandelt. For example, ozone needs to be converted to harmless oxygen, which breaks the chain of photooxidation. Carbon monoxide as a highly toxic gas (even at low concentrations) must non-toxic carbon dioxide can be converted. These contained in the air So far, some pollutants have not been removed or converted.
Die vorliegende Erfindung versucht, diese Schadstoffe durch einen im oder am Kraftfahrzeug angebrachten Katalysator zu entgiften. Er arbeitet somit in der Luft enthaltene Schadstoffe auf.The present invention seeks to remove these pollutants in or on Detoxify automotive mounted catalyst. He works up pollutants contained in the air.
Da der Katalysator am Wasserkühler, Ölkühler oder Luftladekühler aufgebracht oder eingelagert ist, werden große Luftumsatzmengen erreicht. Da diese Kühler beim Betrieb der Fahrzeuge oder Motoren heiß werden, wird die Reaktionsgeschwindigkeit der Katalysatoren stark gesteigert.As the catalyst on the water cooler, oil cooler or air charge cooler applied or stored, large amounts of air turnover are achieved. Because these coolers get hot when operating vehicles or engines the reaction rate of the catalysts becomes strong increased.
Der eingangs angegebene erfindungsgemäße Katalysator ist dadurch gekennzeichnet, daß er entweder als Beschichtung auf sich selbst erhitzende Wasserkühler, Ölkühler oder Luftladekühler aufgebracht ist oder daß er direkt in den Kühler eingearbeitet ist.The catalyst according to the invention specified at the outset is characterized in that it either as a coating on self-heating water coolers, oil coolers or air charge coolers is applied or that it is incorporated directly into the cooler.
Die Beschichtung enthält hitzebeständige Bindemittel, die auch gasdurchlässig sind. Hiermit können bestehende Kühlermodelle ohne Änderungen verwendet werden. Siehe Zeichnung A (1) Kühlermaterial und (2) aufgebrachte Katalysatormasse.The coating contains heat-resistant binders that are also gas-permeable. This allows existing cooler models to be used without changes. See drawing A ( 1 ) cooler material and ( 2 ) catalyst mass applied.
Bei einer Neukonstruktion der Kühler wird die Katalysatormasse entweder als Schüttgutkatalysator, Kugeln, Granulat oder Pellets in den Kühler zwischen den Kühlrippen eingearbeitet. Somit wird eine größere Menge an Katalysatormasse untergebracht.When the cooler is redesigned, the catalyst mass is either as bulk catalyst, spheres, granules or pellets worked into the cooler between the cooling fins. Thus one larger amount of catalyst mass housed.

(1) Kühlermaterial und (2) Katalysatormasse als Schüttgutkatalysator, Kugeln, Granulat oder Pellets. ( 1 ) cooler material and ( 2 ) catalyst mass as bulk catalyst, spheres, granules or pellets.
Zur Umwandlung des Ozons werden Kupferoxide verwendet. Zur Umwandlung des Kohlenmonoxides wird eine Mischung aus Kupferoxiden und Manganoxiden verwendet.Copper oxides are used to convert the ozone. For Conversion of carbon monoxide is a mixture of copper oxides and manganese oxides are used.
Mischungen aus Kupfer- und Manganoxiden werden bereits in großem Umfang in Gasmaskenfiltern verwendet. Diese Oxidmischungen haben aber bei der Anwendung in Gasmasken den gravierenden Nachteil, daß sie durch Wasserdampf vergiftet werden und somit nach einiger Zeit nicht mehr einsatzbereit sind.Mixtures of copper and manganese oxides are already widely used in gas mask filters used. These oxide mixtures have, however, when used in gas masks the serious disadvantage that it is poisoned by water vapor become and therefore no longer operational after some time are.
Da beim erfindungsgemäßen Katalysator die Mischung aus Kupfer- und Manganoxiden auf den Kühler aufgebracht oder in ihn eingearbeitet ist, erhitzen sich die Metalloxide beim Betrieb des Motors und verdampfen somit den Wasserdampf, der normalerweise den Katalysator vergiften würde. Auf diese Weise ist ein kontinuierlicher Gebrauch des Katalysators gegeben, da kein Trocknungsmittel notwendig ist.Since the mixture of copper and manganese oxides in the catalyst according to the invention applied to or incorporated into the cooler the metal oxides during engine operation and evaporate hence the water vapor, which is normally the catalyst would poison. In this way there is continuous use of the catalyst, since no drying agent is necessary.
