Description

Verfahren zur Herstellung von Entfärbungskohle. In der Patentschrift ..1.55 52I ist gezeigt worden, welche Vorteile die Unterteilung des Retortenquerschnittes in einzelne Ringzonen für die Verarbeitung von gleichartigem Rohmaterial verschiedener Stückgröße auf Entfärbungskohle bietet.Process for the production of decolorizing carbon. In the patent specification ..1.55 52I has been shown the advantages of subdividing the retort cross-section into individual ring zones for the processing of the same raw material of different types Offers piece size on decolorizing charcoal.

Durch Versuche wurde festgestellt, daß die beschriebene Vorrichtung die gleichen Vorteile bei der Verarbeitung verschiedener Rohstoffe, deren Stückgröße je nach dem Einzelfall gleich oder verschieden groß zu wählen ist, bewirkt.Experiments have shown that the device described the same advantages when processing different raw materials, their piece size Depending on the individual case, the same or different sizes are to be selected, causes.

Man füllt dann das Rohmaterial, dessen Umwandlung in Entfärbungskohle langsamer und bei höheren Temperaturen erfolgt, in die äußerste Ringzone, die anderen Rohstoffe entsprechend ihrem Verhalten hinsichtlich Umsetzungstemperatur und -geschwindigkeit in die inneren Zonen.The raw material is then filled and converted into decolorizing carbon takes place more slowly and at higher temperatures, in the outermost ring zone, the others Raw materials according to their behavior in terms of reaction temperature and speed in the inner zones.

Auf diesem Wege ist es möglich, Hartholz-und Weichholzkohlen gleichzeitig mit guter Ausbeute und normalen Herstellungskosten zu verarbeiten. Beschickt man z. B. die äußere Ringzone einer Zw-: izonenretorte mir Buchenkohle, die innere mit Nadelholzkohle von gleicher Stückgröße, so kann auch Hartholzkohle auf Entfärbungskohle verarbeitet werden, derenVerarbeitung bisher bekanntlich sehr ungünstig verlief, =wenn nicht ganz unrentabel war. Da in Deutschland speziell Buchenkohle in großen Mengen zur Verfügung steht, so bedeutet deren Verarbeitungsmöglichkeit einen wesentlichen Fortschritt. Aber auch alle übrigen Pflanzenkohlen (z. B.- Rübenblätter- und Stengelkohle, Lupinenkohle und viele andere), die in großen Mengen verfügbar sind, die sich at-er außerordentlich verschieden verhalten, können nach dem vorliegenden Verfahren nutzbringend auf Entfärbungskohle verarbeitet werden.In this way it is possible to use hardwood and softwood coals at the same time process with good yield and normal manufacturing cost. One sends z. B. the outer ring zone of a Zw-: izonenretorte with beech coal, the inner with Coniferous charcoal of the same size, so can hardwood charcoal on decolorization charcoal are processed, the processing of which has been known to have been very unfavorable up to now, = if not completely unprofitable. Since in Germany especially beech coal in large If quantities are available, the processing options are essential Progress. But also all other biochar (e.g. beet leaf and stem charcoal, Lupine charcoal and many others), which are available in large quantities, which are at-er Behave extremely differently, can be beneficial according to the present process processed on decolorizing charcoal.
