Description

Herstellung hochaktiver Kohle Vorliegende Erfindung betrifft die Herstellung hochaktiver Kohle aus Holz oder anderen kohlenstoffhaltigen Stoffen. Das den Gegenstand des Patents 482 174 bildende Verfahren ist dadurch gekennzeichnet, daß man Holz o. dgl. unter Zusatz von Cyan- oder Rhodanverbindungen unter Luftabschluß erhitzt und das Glühprodukt auslaugt mit Salzsäure und Wasser.High Active Coal Manufacture The present invention relates to manufacture highly active charcoal from wood or other carbonaceous substances. That the subject of the patent 482 174 forming process is characterized in that one wood or the like heated with the addition of cyanogen or rhodan compounds in the absence of air and the glow product leaches with hydrochloric acid and water.

Zwecks Verbilligung dieses Verfahrens ersetzt man % bis 2/3 der erforderlichen Rhodanverbindungen durch Alkalien oder Erdalkalien verschiedener Art, man erhält ein dem Produkt des Hauptpatents entsprechendes Erzeugnis bei billigerem Produktionspreis.In order to make this process cheaper,% to 2/3 of the required amount is replaced Rhodane compounds through alkalis or alkaline earths of various kinds are obtained a product corresponding to the product of the main patent at a cheaper production price.

Im Sinne der Gleichung: K,C03 + 2 KHSO4 - KZ S04 -I- CO, + H20 wird nicht ganz die der Gleichung entsprechende Menge Kaliumcarbonat durch Kaliumbisulfat zersetzt, so daß die Reaktionsflüssigkeit noch schwach alkalisch reagiert. Die resultierende Lösung wird mit Rhodankalium verrührt, so daß Kaliumcarbonat, -sulfat und Rhodankalium nebeneinander bestehen. Dieses Salzgemisch hat eine ganz hervorragende Wirkung auf die zu aktivierenden kohlenstoffhaltigen Stoffe und läßt sich direkt auf die Schwelprodukte von Holz, Torf und Braunkohle übertragen, was im Großbetrieb von Wichtigkeit ist.According to the equation: K, C03 + 2 KHSO4 - KZ S04 -I- CO, + H20 the amount of potassium carbonate corresponding to the equation is not completely decomposed by potassium bisulfate, so that the reaction liquid still reacts slightly alkaline. The resulting solution is stirred with potassium rhodium, so that potassium carbonate, sulfate and potassium rhodium coexist. This salt mixture has an excellent effect on the carbon-containing substances to be activated and can be transferred directly to the carbonization products of wood, peat and lignite, which is important in large-scale operations.

Beispie1 33333 g Kaliumcarbonat werden mit 33333 g Kaliumbisulfat zersetzt und in die Reaktionsflüssigkeit 33333 g Rhodankalium eingetragen. Mit dieser Salzlösung werden iooo g Holzkohle imprägniert, getrocknet und etwa 1/2 Stunde bei 7 bis 8oo° unter Luftabschluß erhitzt. Das Glühprodukt wird ausgelaugt mit Salzsäure und Wasser, wobei der wässerige Auszug konzentriert und neuen Versuchen zugeführt wird.Example 33333 g of potassium carbonate are mixed with 33333 g of potassium bisulfate decomposed and entered into the reaction liquid 33333 g of potassium rhodium. With this Salt solution, iooo g of charcoal are impregnated, dried and treated for about 1/2 hour Heated 7 to 8oo ° in the absence of air. The glow product is leached with hydrochloric acid and water, the aqueous extract being concentrated and used for new experiments will.

Gleich vorteilhaft kann das oben angeführte Alkalicarbonat einerseits und das Alkalisulfat andererseits durch andere Alkali- oder Erdalkalisalze ersetzt werden.The above-mentioned alkali metal carbonate can be equally advantageous on the one hand and on the other hand replacing the alkali sulfate with other alkali or alkaline earth salts will.
