Description
Verfahren zur Erzeugung von Ruß aus Methan durch Wärmespaltung. Es ist bekannt (amerikanische- Patentschrift io66894), aus Erdgas oder anderen Methan enthaltenden Kohlenwasserstoffen durch Wärmespaltung Ruß darzustellen. Der auf solche Weise dargestellte Ruß hat eine verhältnismäßig geringe Deckkraft.Process for producing soot from methane by splitting heat. It is known (American patent specification io66894), from natural gas or other methane containing hydrocarbons to produce soot by heat splitting. The one on such Soot represented in this way has a relatively low opacity.
Es wurde nun die Beobachtung gemacht, daß, wenn Erdgase oder mit den Erdgasen wesentlich übereinstimmend zusammengesetzte Gasgemenge mit einer zusätzlichen Menge von bei der Erhitzung keine Kohle abspaltenden Gasen verdünnt werden, die Qualität des aus diesem verdünnten Gase erzeugten Rußes eine wesentlich bessere ist.The observation has now been made that if natural gases or with the Natural gases are essentially composed of a gas mixture with an additional one Amount of gases that do not split off carbon when heated are diluted The quality of the soot produced from this diluted gas is much better is.
Dementsprechend besteht das neue Verfahren zur Erzeugung von Ruß aus reinem oder von Natur aus bereits fremde Gase enthaltenden Methan durch Wärmespaltung darin, daß man das Methan zwecks Steigerung der Reinheit des Produktes vor der Wärmebehandlung mit indifferenten, d. h. bei der Zersetzungstemperatur keine Kohle abspaltenden Gasen in solchen Mengen verdünnt, daß der Gehalt der Mischung an fremden Gasen den üblichen Gehalt von Naturgas an solchen Gasen stets übertrifft.Accordingly, the new method of producing carbon black consists of pure methane or methane which naturally already contains foreign gases through heat splitting in the fact that the methane in order to increase the purity of the product before the heat treatment with indifferent, d. H. No carbon splitting off at the decomposition temperature Gases diluted in such amounts that the content of foreign gases in the mixture The usual content of natural gas in such gases always exceeds.
Der in dieser Weise gewonnene Ruß ist äußerst fein, so daß er sich zur Erzeugung der feinsten Druckfarben eignet und wegen seiner äußerst feinen Verteilung bzw. großen Oberflächenentwicklung auch als absorbierendes bzw. adsorbierendes Mittel mit Vorteil verwenden läßt. Besonders wirksam ist das Verdünnen mit Kohlensäuregas, welches bei der Reaktionstemperatur in Kohlenmonoxyd und Sauerstoff zerfällt, der mit der Kohle gleichfalls Kohlenmonoxyd bildet und in dieser Waise während der Reaktion eine wesentliche Volumenvergrößerung hervorruft.The soot obtained in this way is extremely fine, so that it becomes suitable for the production of the finest printing inks and because of its extremely fine distribution or large surface development also as an absorbing or adsorbing agent can be used with advantage. Dilution with carbonic acid gas is particularly effective, which decomposes into carbon monoxide and oxygen at the reaction temperature, the carbon monoxide also forms with the charcoal, and in this way during the reaction causes a substantial increase in volume.
Durch das Verdünnen des Methans wird nicht nur die Qualität des Produktes ver= bessert, sondern auch die zur Erzielung einer bestimmten Menge Rußes bei sonst gleichen Bedingungen notwendige Zersetzungstemperatur erniedrigt. Die hierdurch erzielte Wärmeersparnis und die Schonung der Apparatur sind weitere Vorteile des neuen Verfahrens.Diluting the methane not only improves the quality of the product improved, but also the one to achieve a certain amount of soot with otherwise The decomposition temperature required under the same conditions is lowered. The result Heat savings achieved and the protection of the equipment are further advantages of the new procedure.
