Description
Verfahren zur Herstellung katalytisch aktivierter KörperProcess for the production of catalytically activated bodies
Die Erfindung betrifft ein Verfahren zur Herstellung katalytisch aktivierter Körper, die vorzugsweise zur vollständigen flammenlosen Verbrennung von Kohlenwasserstoffen zu C0t und H2O einsetzbar sind, wobei die aktivierten Körper insbesondere als Heizelemente Verwendung finden sollen.The invention relates to a method for the production of catalytically activated bodies which can preferably be used for the complete flameless combustion of hydrocarbons to form C0 t and H 2 O, the activated bodies being used in particular as heating elements.
Es sind Heizöfen bekannt, die mit katalytisch wirkenden Heizpolstern aus Asbestfasern mit Platin als Kontakt betrieben werden. Die Herstellung dieser Heizpolster ist durch die Aufarbeitung des Rohasbestes und das Präparieren mit Platin sehr arbeits- und kostenaufwendig und birgt durch den bei der Verarbeitung auftretenden Asbeststaub die Gefahr einer Asbestose Da außerdem zur Füllung eines Polsters größere Mengen Platinasbest notwendig sind, ist der Einsatz wegen des teuren Platins aus ökonomischen Gründen nicht vertretbar.There are heating ovens known with catalytic heating pads made of asbestos fibers with platinum as a contact. The manufacture of this heating pad is through the work-up The raw asbestos and the preparation with platinum are very labor-intensive and costly and contain due to the processing Occurring asbestos dust increases the risk of asbestosis Since larger quantities of platinum asbestos are also used to fill a cushion are necessary, their use is not justifiable for economic reasons because of the expensive platinum.
Es ist weiterhin bekannt, daß außer den Asbestfasern Schlackenwolle/ Quarzwolle, Kieselgur, Bimsstein und ähnliche Materiiilien als Kontaktträger geeignet sind, jedoch als Katalysatoren zur flammenlosen Verbrennung von Kohlenwasserstoffen keine Verwendung finden.It is also known that besides the asbestos fibers, slag wool / Quartz wool, kieselguhr, pumice stone and similar materials are suitable as contact carriers, but not as catalysts for the flameless combustion of hydrocarbons Find use.
Es sind auch Verfahren bekannt, bei denen als Kontaktträger Glasfaser-Malimogewebe eingesetzt wurde (DD-PS 84842). Ein industrieller Einsatz dieser Polster ist jedoch nicht erfolgt. Desweiteren sind Verfahren zur Herstellung von Kontakten bekannt, wobei als Kontaktträger Al2O, oder Aluminiumsilikate verwendet wurden. Eine Verwendung von Aluminiumsilikatfasern in Form von porösen Schichten als Kontaktträger ist nicht bekannt, und über einen Einsatz als Katalysator zur flammenlosen Verbrennung von Kohlenwasserstoffen liegen keine Angaben vor.Methods are also known in which glass fiber Malimo fabric was used as the contact carrier (DD-PS 84842). However, these cushions have not been used industrially. Furthermore, methods for producing contacts are known, Al 2 O or aluminum silicates being used as contact carriers. The use of aluminum silicate fibers in the form of porous layers as contact carriers is not known, and no information is available about their use as a catalyst for the flameless combustion of hydrocarbons.
Das Ziel der Erfindung ist die Herstellung eines wenig arbeits- und kostenaufwendigen Katalysators aus nicht gesundheitsschädigendem Material mit geringem Platinanteil zur flammenlosen Verbrennung von Kohlenwasserstoffen in gleichbleibender Qualität.The aim of the invention is to produce a little labor and expensive catalytic converter made of non-harmful material with a low platinum content for flameless Combustion of hydrocarbons of constant quality.
Der Erfindung liegt die Aufgabe zugrunde, einen zur flammenlosen Verbrennung von Kohlenwasserstoffen geeigneten schichtförmigen und saugfähigen Kontaktträger aus temperaturbeständigem, nicht gesundheitsschädigendem Material zu entwickeln, auf den ein Oxydationskatalysator als Kontakt aufgebracht werden kann.The invention is based on the object of providing a layered material suitable for the flameless combustion of hydrocarbons and to develop absorbent contact carriers made of temperature-resistant, non-harmful material, to which an oxidation catalyst can be applied as a contact.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß flächige Schichten aus keramischen Fasern mit Edelmetallverbindungen der Platingruppe getränkt und durch thermische Behandlung aktiviert werden.According to the invention the object is achieved in that flat Layers of ceramic fibers impregnated with noble metal compounds of the platinum group and activated by thermal treatment will.
Die Erfindung soll anhand eines Ausführungsbeispieles näher erläutert werden. Die nach dem erfindungsgemäßen Verfahren präparierte Faserschicht soll als Heizelement Verwendung finden.The invention is to be explained in more detail using an exemplary embodiment. According to the method according to the invention The prepared fiber layer should be used as a heating element.
Die Herstellung der mit Platin präparierten kermamischen Faserschichten ist ohne besondere Vorbehandlung und mit einfachen Mitteln durchzuführen. Die Faserschichten werden einzeln in gleiche Volumina einer alkoholischen H,PtClfi-Lösung in derThe production of the ceramic fiber layers prepared with platinum can be carried out without any special pretreatment and with simple means. The fiber layers are individually in equal volumes of an alcoholic H, PtCl fi solution in the
-1 Konzentration von 0,005 bis 0,01 mol 1 eingelegt und bis zur Grenze der Saugfähigkeit getränkt. Die Saugfähigkeit ist bei wechselnder Größe und Schichtstärke jeweils vorher zu ermitteln. Die Abmessung gleicher Volumina erfolgt durch eine Dosiereinrichtung aus einem Vorratsbehälter. Die getränkten Faserschichten werden zur Reduktion des 4-wertigen Platins zum metallischem Platin abgebrannt, zur Nachreduktion 5 bis 20 min bei 500 bis 600 0C geglüht, nach Erkalten in ein Siebgewebe eingelegt und durch Auflegen einer unpräparierten Faserschicht oder einer gleichmäßigen Schicht aus losen vorgeglühten AIuminiumsilikatfasern oder anderen bekannten wärmebeständigen Materialien zum Heizelement komplettiert. Mit diesen Heizelementen wird die gleiche flammenlose Verbrennung von Benzinen im Siedebereich von 60 bis 130 0C, als auch von verflüssigten Kohlenwasserstoffen wie Propan, bei einer Katalysatoroberflächentemperatur von 290 bis 320 0C erreicht, wie mit den bisher eingesetzten Asbestpolstern.-1 concentration of 0.005 to 0.01 mol 1 inserted and soaked up to the limit of absorbency. The absorbency must be determined beforehand if the size and layer thickness change. The same volumes are measured by a metering device from a storage container. The impregnated fiber layers are burned for reduction of the 4-valent platinum to metallic platinum, the afterreduction 5 to 20 minutes at 500 to 600 0 C annealed, pickled after cooling in a mesh and preannealed by placing a unprepared fiber layer or a uniform layer of loose AIuminiumsilikatfasern or other known heat-resistant materials for the heating element. With these heating elements is the same flameless combustion of gasoline boiling range from 60 to 130 0 C, to be achieved also in the liquified hydrocarbons such as propane, at a catalyst surface temperature of 290-320 0 C, as with the previously used asbestos pads.
