Description

Verfahren zur Herstellung von Entfärbungskohle. Die Erfindung , betrifft ein Verfahren zur Herstellung von Entfärbungskohle. Die nach diesem Verfahren erlangte Kohle ist frei von schädlichen Beimischungen und eignet sich hauptsächlich zum Gebrauch in der Ölraffinerie als Entfärbungsmittel. Die Kohle eignet sich nicht nur zum Entfärben, sondern auch als Reinigungsmittel und kann bei den verschiedensten chemischen Prozessen Anwendung finden.Process for the production of decolorizing carbon. The invention relates to a process for the production of decolorizing carbon. Which obtained through this procedure Coal is free from harmful admixtures and is mainly suitable for use in the oil refinery as a decolorizing agent. The charcoal is not only suitable for decolorizing, but also as a cleaning agent and can be used in a wide variety of chemical processes Find application.

Für vorliegendes Verfahren werden die Rückstände aus den Filterpressen beim Raffinieren von Speiseöl wie Baumwollsamenöl, Öl aus den Nüssen des Butterbaumes u. dgl. als Ausgangsstoffe benutzt. Diese Rückstände enthalten Öl und Spuren von Seifen, Walkererde oder ähnliche Mischungen, sowie möglicherweise tierische Kohle, Spuren von Flüssigkeit, freie Fettsäuren und einige Farbstoffe.For this procedure, the residues from the filter presses are used when refining cooking oil such as cottonseed oil, oil from the nuts of the butter tree and the like. Used as starting materials. These residues contain oil and traces of Soaps, fuller's earth or similar mixtures, and possibly animal charcoal, Traces of fluids, free fatty acids and some colorings.

Die Rückstände werden gemäß vorliegender Erfindung in einem Flammenofen oder einem anderen Ofen verkohlt, wobei die flüchtigen Teile austreten und verbrennen und schließlich ein trockener, poröser, kohleartiger Körper zurückbleibt, wobei sich zu gleicher Zeit die im Ausgangsstoff enthaltene Seife in alkalische Salze umwandelt.The residues are in accordance with the present invention in a flame oven or another furnace, causing the volatile parts to escape and burn and finally a dry, porous, carbon-like body remains, wherein At the same time, the soap contained in the starting material turns into alkaline salts converts.

Läßt man die Verkohlung unter Zuführung von Luft vor sich gehen, so bildet sich nebenher Ruß, der sich in großen Mengen an den kühlen Oberflächen in Höhlungen dcs Abzuges niederschlägt. Die Behälter, welche das kohleartige Material aufnehmen, werden alsdann aus dem Ofen herausgebracht und sofort bedeckt, um jeden weiteren Luftzugang zu verhindern. Sind die Massen genügend abgekühlt, so werden sie in bekannter Weise in Gefäßen oder Behältern mit geeigneten Rührmitteln mit verdünnter Säure, wie z. B. Salzsäure, ausgewäschen. .If the charring is allowed to proceed with the addition of air, so Soot forms at the same time, which is found in large quantities on the cool surfaces in Cavities of the deduction are reflected. The containers that hold the coal-like material are then taken out of the oven and covered at once for everyone to prevent further air access. If the masses have cooled down sufficiently, they become in a known manner in vessels or containers with suitable stirring means dilute acid, such as B. hydrochloric acid, washed out. .

Nach der Neutralisierung gelangt die Masse zu einer Brikettpresse, wo sie unter hohem Druck zu Briketts geformt wird. Die Briketts werden hernach, wenn es erforderlich erscheint, wieder in kleinere Stücke zerbrochen und in einem Flammenofen erhitzt, damit die Feuchtigkeit und die Säure ausgetrieben werden und die Kohle leichter und poröser wird. Die Kohlenstücke können schließlich noch, wenn es erforderlich erscheint, nach bestimmten Größen gesiebt werden.After neutralization, the mass goes to a briquette press, where it is formed into briquettes under high pressure. The briquettes are afterwards if necessary, broken again into smaller pieces and combined into one Flame oven heated so that the moisture and acid are driven out and the coal becomes lighter and more porous. The coal pieces can finally still, if it appears necessary to be sieved according to certain sizes.
