Description
Verfahren zur Verhinderung der Abscheidung von Kohlenstoff in und auf erhitzten keramischen Materialien Es ist bekannt, daß Eisen oder Eisenoxyd enthaltende keramische Massen bei höheren Temperaturen aus kohlenstoffhaltigen Gasen, wie z. B. Generatorgas, Kohlenstoff abscheiden. Dadurch werden in der Regel die Steine nicht nur oberflächlich verändert, sondern auch in ihrem inneren Gefüge zerstört. In bestimmten Fällen, z. B. bei Regeneratoren, werden auch ohne eigentliche Zerstörung infolge Verstopfung der Poren mit Kohlenstoff und dadurch bewirkte Behinderung des Wärmeaustausches die Steine unbrauchbar.Method of preventing the deposition of carbon in and on heated ceramic materials It is known that iron or iron oxide containing ceramic masses at higher temperatures from carbon-containing gases, such as. B. generator gas, deposit carbon. This usually causes the stones not only changed on the surface, but also destroyed in their inner structure. In certain cases, e.g. B. with regenerators, are also without actual destruction as a result of clogging of the pores with carbon and the resulting obstruction of the Heat exchange makes the stones unusable.
Es wurde nun die überraschende Beobachtung gemacht, daß die Kohlenstoffabscheidung in und auf keramischen Materialien, die in der Hitze mit kohlenstoffhaltigen Gasen in Berührung kommen, vermieden wird, wenn man diesen Materialien Kupfer zuführt. Es ist dabei gleichgültig, ob das Kupfer schon bei der Herstellung des keramischen Körpers durch Verwendung kupferhaltiger Ausgangsstoffe oder durch Zugabe, zweckmäßig in Form einer Lösung oder Suspension, in irgendeinem Stadium des Fabrikationsprozesses oder erst dem Fertigfabrikat oder dem daraus hergestellten Gegen stand durch Mischen, Tränken, Bespritzen, Bepinseln oder in sonst einer geeigneten Weise zugeführt wird.The surprising observation has now been made that the carbon deposition in and on ceramic materials that are exposed to heat with carbonaceous gases come into contact is avoided by adding copper to these materials. It does not matter whether the copper is already used in the manufacture of the ceramic Body by using copper-containing raw materials or by adding, expedient in the form of a solution or suspension, at any stage of the manufacturing process or only the finished product or the object manufactured from it by mixing, Soaking, spraying, brushing or in any other suitable manner is supplied.
Wird das Kupfer schon bei der Herstellung den keramischen Massen zugeführt, so genügt es, wenn nur der eisenhaltige Bestandteil des zur Herstellung der keramischen Masse verwendeten Ausgangsmaterials mit kupferhaltigen Stoffen oder deren Suspensionen oder Lösungen behandelt wird.If the copper is added to the ceramic mass during manufacture, it is sufficient if only the ferrous component is used to manufacture the ceramic Mass of raw material used with copper-containing substances or their suspensions or solutions is dealt with.
Unter Umständen kann auch fein verteiltes Kupfer, z. B. in Form von Bronzepulver, benutzt werden.Finely divided copper, e.g. B. in the form of Bronze powder.
Den keramischen Körpern, deren Ausgangsmaterialien oder den Kupferlösungen können, um die Aufnahme des Kupfers zu fördern, mit Vorteil Benetzungsmittel beliebiger Art, wie z. B. alkylierte aromatische Sulfosäuren oder deren Salze, zugegeben werden. Beispiel Chamottesteine werden mit einer ro°/oigen ammoniakalischen Kupfersulfatlösung benetzt oder einige Minuten in die Lösung eingetaucht, worauf man sie nach dem Herausnehmen abtropfen läßt.. Die so erhaltenen Steine werden an der Luft getrocknet. Sie zeigen, z. B. bei ihrer Verwendung als Futtersteine in einem Braunkohlengenerator, nach längerem Gebrauch keinerlei Kohlenstoffablagerung.The ceramic bodies, their starting materials or the copper solutions In order to promote the uptake of the copper, any wetting agent with advantage can be used Kind such as B. alkylated aromatic sulfonic acids or their salts are added. Example Chamotte stones are made with a ro% ammoniacal copper sulphate solution wetted or immersed in the solution for a few minutes, after which you can they drain after taking them out .. The stones obtained in this way are attached to the Air dried. They show z. B. when used as lining stones in one Lignite generator, no carbon build-up after prolonged use.
