Description

Herstellung einer hochaktiven Kohle in körniger Form In dem Patent 461 884 ist ein Verfahren zur Herstellung hochaktiver Entfärbungskohle beschrieben, das darin besteht, daß kohlenstoffhaltiges, mit Alkaliverbindungen versetztes Material beliebiger Herkunft unter Zusatz von Kalisulfiden oder Kaliumpolysulfidenund gegebenenfalls von Alkalicarbonaten geglüht wird. Wird nach diesem Verfahren formloses Holz .aktiviert, so läßt sich dasselbe nach dem Aktivierungsprozeß ohne Bindemittel nicht mehr in festgefugte Formen bringen. Überraschenderweise stellte es sich heraus, daß bei Kornform des zu aktivierenden Materials vor der Aktivierung der Aktivierungsgrad einerseits in keiner Weise vermindert, anderseits die Form erhalten bleibt, indem vegetabilische Rohstoffe, wie Holz, Kork o. dgl., ihre Struktur nicht verlieren.Manufacture of a high-active carbon in granular form In the patent 461 884 describes a process for the production of highly active decolorizing carbon, that consists in the carbonaceous material mixed with alkali compounds of any origin with the addition of potassium sulfides or potassium polysulfides and optionally is calcined by alkali carbonates. If shapeless wood is activated according to this process, so the same can no longer be used without a binder after the activation process bring solid forms. Surprisingly, it turned out that at Grain shape of the material to be activated before activation, the degree of activation on the one hand in no way diminished, on the other hand the shape is retained by Vegetable raw materials such as wood, cork or the like do not lose their structure.

Beispiel Zoo Teile Holz, Korkabfälle oder sonstige Vegetabilien in körniger Form werden mit 3o Teilen Pottasche und 15 Teilen Schwefelkalium imprägniert, in einem Muffelofen stark geglüht und nach beendetem Glühprozeß mit Wasser abgeschreckt, ausgelaugt und gegebenenfalls noch mit Salzsäure behandelt. Die fertige Kohle wird vom Abfall. grus abgesiebt und dieser Abfall feiest gemahlen und als hochwertige Pulverkohle verwandt. Die durch die Auslaugung wiedergewonnene Schwefelkalium-Pottasche-Lösung wird unmittelbar zur Aktivierung weiteren Materials benutzt.Example zoo parts wood, cork waste or other vegetables in granular form are impregnated with 3o parts of potash and 15 parts of potassium sulphide, Annealed in a muffle furnace and quenched with water after the annealing process has ended, leached and optionally treated with hydrochloric acid. The finished coal will from rubbish. Grus is sieved off and this waste is ground up and classified as high-quality Related to powder charcoal. The potassium sulphide-potash solution recovered by the leaching is used immediately to activate further material.

Eine andere Ausführungsform des Verfahrens besteht beispielsweise darin, daß. man z. B. 1 oo Teile Holz o. dgl. von Kornform mit 3o bis 4o Teilen Schwefelleber oder Schwefelkalium tränkt und dann wie oben weiterverfährt.Another embodiment of the method exists, for example in that. one z. B. 1 oo parts of wood or the like of grain shape with 3o to 4o parts Sulfur liver or potassium sulfur soak and then proceed as above.
