Description
Herstellung von aktiver Kohle Bei der Reinigung von Erdöl- oder Steinkohlenteerfraktionen mit Schwefelsäure resultieren sogenannte Säureteere, deren Natur noch nicht genügend erforscht worden ist. Diese Säureteere bilden, wie gefunden wurde, ein wertvolles Ausgangsmaterial für die Herstellung aktiver Kohle. Wenn man besonders die sogenannten wasserlöslichen Säureteere mit Kaliumsulfid oder Pottasche oder Kaliumhydroxyd neutralisiert, durch Verdampfen zur Trockne bringt und die gebildeten Körpergemische rasch auf hohe Temperaturen, auf etwa iooo°, erhitzt, mit oder ohne Zufügung von Luftsauerstoff, Kohlendioxyd oder Wasserdampf oder Gemischen dieser behandelt, dann erhält man ein Endprodukt, das man entweder durch Ablöschen mit Wasser oder durch Erkaltenlassen im luftfreien Gasstrom, z. B. Rauchgasen, Stick-. stoff u. dgl., und nachfolgendem Behandeln mit Wasser von anorganischen Bestandteilen befreien kann. ?Nach erfolgtem Trocknen und nochmaligem Ausglühen in sauerstofffreier oder sauerstoffarmer Atmosphäre erhält man eine besonders großoberflächige, ausgezeichnete aktive Kohle aus dem außerordentlich billigen Ausgangsprodukt, für das man bis jetzt eine wirtschaftliche Verwendung nicht hat.Production of active coal In the purification of petroleum or coal tar fractions with sulfuric acid so-called acid tars result, the nature of which is not yet sufficient has been researched. These acid tars are found to be valuable Starting material for the production of active charcoal. If you especially the so-called water-soluble acid tars neutralized with potassium sulfide or potash or potassium hydroxide, brings it to dryness by evaporation and quickly applies the body mixtures formed high temperatures, heated to around iooo °, with or without the addition of atmospheric oxygen, Treated carbon dioxide or steam or mixtures of these, then one obtains a End product that can be obtained either by extinguishing with water or by letting it cool down in the air-free gas stream, e.g. B. flue gases, stick. fabric and the like, and the following Treatment with water can remove inorganic constituents. ? After done Drying and re-annealing in an oxygen-free or oxygen-poor atmosphere you get a particularly large, excellent active carbon from the extraordinarily cheap starting product, for which up to now an economical one Use does not have.
