Description

Verfahren zur Herstellung von aktiver Kohle. 1s wurde gefunden, claß man eine hochaktive Kohle, die in gleicher Weise für katalytische, Absorptions- und Entfärbungszwecke ganz hervorragend geeignet ist, dadurch erhält, daß man geeignete, beirr Frhitzen Kohlenstoff liefernde Substanzen, wie Holz, Braunkohle u. dgl., mit Ameisensäure oder Oxalsäure oder deren Salzen, insbesondere Alkalisalzen, erhitzt und das erhaltene Produkt ztveckmäßig durch Auswaschen von den löslichen Bestandteilen befreit. In ,gleicher Weise kann man durch Benutzung feuerfester Träger und vorzugsweise flüssiger oder gelöster kohlehaltiger Stoffe. auch Kohlesteine, namentlich für katalytische Zwecke. herstellen.Process for the production of active charcoal. 1s was found, class a highly active carbon, which is used in the same way for catalytic, absorption and decolorization purposes is very well suited, by obtaining suitable, When heated, substances that provide carbon, such as wood, lignite and the like, are included Formic acid or oxalic acid or their salts, in particular alkali salts, heated and the product obtained by washing out the soluble components freed. In the same way one can use refractory supports and preferably liquid or dissolved carbonaceous substances. also coal stones, especially for catalytic ones Purposes. produce.

Beispiel. Gekörnte Braunkohle (auch Braunkohlenbrikett) wird mit einer Lösung voti 5o bis ioo Prozent ihres Gewichtes an Kaliumoxalat getränkt, getrocknet und bis zur hellen Rotglut erhitzt. Die erhaltene Kohle wird zweckmäßig mit Wasser oder .Salzsäure gewaschen und getrocknet. Zur Herstellung von ähnlich wirkendem Kohlestein wird z. B. eine gekörnte feuerfeste Masse, wie Bimsstein oder Diatomitstein. mit einer gemischten Lösung von Melasse und Kaliumoxalat getränkt ttnd erhitzt.Example. Grained lignite (also known as lignite briquette) is made with a Solution from 50 to 100 percent of its weight soaked in potassium oxalate, dried and heated to a bright red glow. The coal obtained is expediently mixed with water or. hydrochloric acid washed and dried. For the production of similar looking Coal stone is z. B. a granular refractory mass, such as pumice stone or diatomite stone. soaked and heated with a mixed solution of molasses and potassium oxalate.
