Verfahren zur Gewinnung und Wiederbelebung von Entfärbungskhle grosser
Entfärbungskraft.
Durch das Patent Nr. 68169 ist ein Verfahren geschützt, nach welchem Entfärbung- kohle von hoher Entfärbungskraft dadurch erhalten wird, dass man kohlenstoffhaItige Substanzen aller Art, wie Zellulose, Sägespäne, Torf, Braunkohle, Steinkohle, tierische Abfälle usw., mit Chlorzink erhitzt.
Dabei muss das Erhitzen, wio aus dem Beispiel in der Patentschrift hervorgeht, bis zur Destillation des Chlorzinks getrieben werden.
Es ist nun gefunden worden, dass es nicht erforderlich ist, die Mischung von organischer Substanz mit Chlorzink bis zur Destillation des Chlorzinks zu erhitzen, um die Überführung der organischen Substanz in hochwertige Entfärbungskohle herbeizuführen, sondern, dass es vollkommen ausreichend ist, die Mischung von organischer Substanz mit Chlorzink auf solche Temperaturen zu erhitzen, bei welchen noch keine Verflüchtigung des Chlorzinks eintritt, insoferne die Mischung nur so lange bei solchen Temperaturen erhitzt wird, bis unter dem Einflusse des wasserfreien Chlorzinks die Umwandlung der organischen Substanz in aktiven Kohlenstoff erfolgt ist.
Dieses neue Verfahren bedeutet gegenüber dem Verfahren nach Patent Nr. 68 in 9 einen, wesentlichen technischen Fortschritt. Infolge der niederen in Betracht kommenden Reaktionstemperaturen ist der Verbrauch an Heizstoff bei dem neuen Verfahren ein ge- ringerer und es entfällt, da bei diesen Temperaturen eine Verflüchtigung von Chlorzink nicht stattgefunden hat, die Notwendigkeit der Kondensation von Chlorzinkdämpfen, welche Kondensation bei dem Verfahren nach Patent Nr. 68169 aus wirtschaftlichen Gründen notwendig ist, und weiter ist es möglich, den Prozess bei dieser niederen'TCll1- peratur in einer Apparatur aus Metall, z. B.
Eisen, zu Ende zu führen, was bei dem Verfahren nach Patent Nr. 68169 wirtschaftlich deshalb nicht möglich ist, da die auf- tretenden Cblorzinkdämpfe eine rasche Zerstörung des Eisens herbeiführen würden.
Wie das Verfahren nach Patent Nr. 68169. so kann das den Erfindungsgegenstand bildende Verfahren zur Wiederbelebung von Entfärbungskohlen jeder Herkunft Anwendung Sndcn.

Process for the recovery and revitalization of decolorization cooler
Discoloration power.
Patent no. 68169 protects a process according to which decolorizing carbon with high decolorizing power is obtained by heating all kinds of carbonaceous substances, such as cellulose, sawdust, peat, lignite, hard coal, animal waste, etc., with zinc chloride.
The heating, as can be seen from the example in the patent, must be carried out until the chlorine-zinc is distilled.
It has now been found that it is not necessary to heat the mixture of organic matter with zinc chloride until the zinc chlorine is distilled in order to bring about the conversion of the organic matter into high-quality decolorizing carbon, but that it is completely sufficient to mix the organic To heat the substance with zinc chloride to temperatures at which the zinc chlorine does not volatilize, provided that the mixture is only heated at such temperatures until the organic substance has been converted into active carbon under the influence of the anhydrous zinc chlorine.
This new process represents a significant technical advance over the process according to patent no. As a result of the lower reaction temperatures in question, the consumption of heating fuel is lower in the new process and, since there was no volatilization of zinc chloride at these temperatures, there is no need for condensation of zinc chloride vapors, which condensation in the process according to the patent No. 68169 is necessary for economic reasons, and it is also possible to carry out the process at this lower temperature in an apparatus made of metal, e.g. B.
Iron to complete, which is not economically feasible with the process according to patent no. 68169, since the carbon-zinc vapors that occur would cause the iron to be destroyed quickly.
Like the process according to patent no. 68169, the process forming the subject of the invention for the revitalization of decolorizing carbons of any origin can be used.
