Description

Verfahren zur Herstellung hochaktiver Kohle. Bekanntlich kann man Holz und ähnliche Materialien durch geeignete Mittel in hochaktive Kohle überführen. Benutzt man an Stelle des Holzes Torf oder Braunkohle und behandelt diese nach einem derartigen Verfahren zwecks Überführung in aktive Kohle, so hat diese Kohle gegenüber der aus Holz hergestellten den Nachteil, zu voluminös zu sein und eine für viele Fälle der Praxis zu geringe Härte zu besitzen.Process for the production of highly active coal. As is well known, you can Use suitable means to convert wood and similar materials into highly active charcoal. If you use peat or lignite instead of wood and treat them according to one such a process for the purpose of conversion into active charcoal, this charcoal has opposite those made of wood have the disadvantage of being too bulky and one for many Cases of having too little hardness in practice.

Es wurde nun gefunden, daß man Torf und Braunkohle für die Herstellung der aktiven Kohle ohne die eben angeführten Nachteile nutzbar machen kann, indem man ein Gemisch von zerkleinertem Holz, beispielsweise Sägemehl, mit den erwähnten Materialien. gegebenenfalls nach Imprägnierung .mit den erforderlichen Materialien bzw. Anfeuchtung, in geeignete Formen preßt, die man dann gegebenenfalls auch durch Schneiden u. dgl. zerkleinern kann, und die so erhaltenen Preßstücke in beliebiger Apparatur der Verkohlung unterwirft. Man erhält so, unter Benutzung der erwähnten billigen Ausgangsmaterialien, eine hochaktive Kohle von einer Härte, die derjenigen der aus Holzstücke allein hergestellten nicht nachsteht und sich auch im Schüttgewicht von dieser praktisch nicht unterscheidet. Die Absorptionsfähigkeit der neuen Kohle ist größer als diejenige der letzterwähnten.It has now been found that peat and lignite can be used for the production the active charcoal can be made usable without the disadvantages just mentioned by a mixture of crushed wood, for example sawdust, with the mentioned Materials. if necessary after impregnation with the required materials or moistening, pressed into suitable molds, which you then also through if necessary Cutting and the like can comminute, and the pressed pieces thus obtained in any Apparatus subjected to charring. One obtains so, using the mentioned cheap raw materials, a highly active carbon with a hardness equal to that of those that is not inferior to that made from pieces of wood alone and also in terms of bulk weight practically indistinguishable from this. The absorbency of the new coal is larger than that of the last mentioned.

Beispiel: r oo Teile Torf werden gemahlen und mit So Teilen Sägemehl vermischt, mit einer Lösung von Phosphorsäure getränkt, und nach vollständiger Durchmischung in beliebige Formen gepreßt, die gegebenenfalls noch in beliebiger Weise zerkleinert werden können. Die Verkohlung erfolgt in beliebiger Art, beispielsweise im Drehofen.Example: r oo parts of peat are ground and so parts sawdust mixed, soaked with a solution of phosphoric acid, and after complete mixing pressed into any shape, which may be crushed in any way can be. The charring takes place in any way, for example in a rotary kiln.
