Description

Verkohlung der organischen Bestandteile von Sulfitzellstoffablauge. Es ist bekannt, die organischen Bestandteile von Sulfitzellstoffablage bei hohem Druck und hohen Temperaturen oder bei Gegenwart von Salzlösungen bei mäßiger Temperatur zu verkohlen. Es wurde nun gefunden, daß man auch ohne Salzlösungen eine Verkohlung erreichen kann, wenn man die Sulfitablauge von einem Stoff mit großer Oberflächenentwicklung, etwa Adsorptionskohle, ferner Torf, Braunkohle, Kasseler Braunkohle. Halbkoks von der Tieftemperaturverkohlung, Ton u. dgl., aufsaugen läßt und auf Temperaturen erhitzt, die im allgemeinen 200° nicht zu überschreiten brauchen. Durch die .gtisbreitung der zweckmäßig vorher schon eingedickten Sulfitablauge auf sehr große Oberflächen geht deren Zersetzung verhältnismäßig sehr rasch und glatt vor sich. Man erhält Kohle, die ihrerseits wieder zur Ausübung des Verfahrens dienen kann, so daß sich das Adsorptionsmittel für die Sulfitablauge im Verkohlungsprozeß selbst stets aufs neue erzeugt. Gegebenenfalls kann auch ein Zusatz von Säure bei der Erhitzung gegeben werden. Man kann das Verfahren beispielsweise wie folgt ausführen.Charring of the organic components of sulphite pulp liquor. It is known to deposit the organic components of sulfite pulp at high levels Pressure and high temperatures or in the presence of saline solutions at moderate temperature to char. It has now been found that charring can also occur without salt solutions can be achieved if one removes the sulphite liquor from a substance with a large surface development, such as adsorption coal, as well as peat, lignite, Kassel lignite. Semi-coke from the low-temperature carbonization, clay and the like, can be soaked up and heated to temperatures, which generally do not need to exceed 200 °. Through the .gtis spread the sulphite waste liquor, expediently already thickened, on very large surfaces their decomposition proceeds relatively quickly and smoothly. You get Coal, which in turn can be used to carry out the process, so that the adsorbent for the sulphite waste liquor in the charring process itself is always on new ones generated. If necessary, acid can also be added during the heating will. The method can be carried out, for example, as follows.

B c i s p i e 1 : In einen Stilfitzellstoffkoelier werden 70o Teile Adsorptionskohle, wie sie beispielsweise durch Verkohlung von Holzabfällen vermittels Chlorinagnesiumlaugen gewonnen werden kann, gegeben und 20oo Teile eingedickter Sulfitablatige (entsprechend 8ooo Teilen frischer Stilfitablauge) eingerührt, derart, daß eine sehr dickbreiige Mhsse entsteht. Nachdem noch 2 Prozent vom Gewicht der in der Sulfitablauge enthaltenen organischen Substanz an Salzsäure hinzugegeben sind, wird das Druckgefäß verschlossen und die Temperatur unter Abdestillation eines Teiles der Flüssigkeit auf i 8o° gebracht und diese Temperatur 8 Stunden aufrechterhalten. Nach dieser Zeit wird der 1o Atm. im allgemeinen nicht übersteigende Druck abgeblasen, hierauf die Kohle teilweise dein Gefäß entnommen, worauf aufs neue Sulfitablauge eingefüllt und der Prozeß der Verkohlung wiederholt wird.B c i s p i e 1: 70o pieces are put into a Stilfitzellstoffkoelier Adsorption charcoal, such as that mediated, for example, by charring wood waste Chlorinagnesiumlaugen can be obtained, given and concentrated 20oo parts Sulphite tablets (corresponding to 8,000 parts of fresh Stilfit waste liquor) stirred in, in such a way that that a very thick pulp results. After another 2 percent of the weight of the Organic substance contained in the sulphite waste liquor is added to hydrochloric acid are, the pressure vessel is closed and the temperature is distilled off a Part of the liquid brought to i 80 ° and this temperature maintained for 8 hours. After this time the 10 atm. generally not excessive pressure blown off, then some of the coal was removed from your vessel, whereupon new sulphite waste liquor filled and the process of charring is repeated.

Im Destillat erhält man neben anderen Stoffen gewisse Mengen von schwefliger Säure und Methylalkohol, dis nutzbar gemacht werden k;",nnen. Die Kohle selbst gibt beim Waschen ungefärbte Abwässer. Sie kann nach dem Trocknen in einer Staubfeuerung verbrannt bzw. brikettiert werden. Man erhält etwa 5o Prozent der in der Sulfitablauge enthaltenen organischen Substanz als Kohle.In addition to other substances, certain quantities of sulphurous substances are obtained in the distillate Acid and methyl alcohol, which can be made usable; ", can. The coal itself gives uncolored wastewater when washing. After drying, it can be put in a dust heater be burned or briquetted. About 50 percent of that in the sulphite waste liquor is obtained contained organic matter as coal.
