Description

Verfahren zur Herstellung einer hochaktiven Kohle. Inder Patentschrift 43 8 67 0 ist ein Verfahren zur Herstellung einer hochaktiven Kohle b#eschrieben, das darin besteht, daß man Holz oder andere cellulosehaltige Stoffe mit Bisulfat imprägniert,bei Temperaturen oberhalb 5oo' glüht und die erhaltene Masse auslaugt, wobei man gleichzeitig als wertvolles -Nebenprodukt Schwefelnatrium in Lösung erhält.Process for the production of a high-active carbon. Patent specification 43 8 67 0 describes a process for the production of a highly active charcoal, which consists in impregnating wood or other cellulose-containing substances with bisulfate, annealing at temperatures above 500 'and leaching out the mass obtained, which is also valuable -The by-product contains sodium sulphide in solution.

Es hat sich nun gezeigt, daß das gleiche Ergebnis erzielt wird, wenn man das Holz oder die cellulosehaltig-en Stoffe statt mit Bisulfat mit einem Gemisch von Natriumsulfat und Ammoniumsulfat imprägniert, glüht und die Masse auslaugt. Bei dem Glü'hprozeß bildet sich aus dem Natrium- und Ammonium.-sulfat unter Freiwerden von Ammoniak primär das Bisulfat, so daß schließlich wie bei dem Hauptverfahren gleichfalls Schwefelnatrium in Lösung als Nebenprodukt entsteht. Die auf die beschriebene Weise erhältliche Kohle hat die gleichen hervorragenden Absorptions- und Entfärhungseigenschaften, wie die nach dem Hauptverfahren dargestellte. B eispiel.It has now been shown that the same result is achieved if the wood or the cellulosic substances instead of bisulfate with a mixture impregnated by sodium sulphate and ammonium sulphate, it glows and leaches the mass. During the annealing process, the sodium and ammonium sulphate is formed and released of ammonia primarily the bisulfate, so that finally as in the main process likewise sodium sulphide is formed as a by-product in solution. The on the described Coal obtainable in this way has the same excellent absorption and decolouring properties, like the one shown after the main procedure. Example.

Zerkleinertes Holz wird mit einer starken Lösung eines Gemisches von Natriumsulfat und Ammoniumsulfat getiänkt, getrocknet und zweckmäßig bei Luftabschluß geglüht. Nach dem Erkalten wird mit Wasser ausgelaugt. Die erhaltene I,#-,ohle ist sofort oder nach Auswaschen mit Salzsäure und nachfolgendem Trocknen verwendungsfähig.Crushed wood is treated with a strong solution of a mixture of Sodium sulphate and ammonium sulphate soaked, dried and expedient in the absence of air annealed. After cooling, it is leached with water. The I, # -, ohle obtained is Can be used immediately or after washing with hydrochloric acid and subsequent drying.
