Description

Herstellung kieselsäurehaltiger aktiver Kohle Zusatz zum Patent 453972 Es wurde gefunden, daß man nach dem Verfahren des Patents 453 972 zu einer hochaktiven, besonders zu katalytischen Zwecken geeigneten, weniger leicht brennbaren Kohle in Kornform auf sehr einfache Weise gelangt, wenn man von bereits vorverkohlter, gekörnter inaktiver Kohle beliebiger Herkunft ausgeht. Tränkt man z. B. gekörnte Kohle mit einer Säurelösung und läßt dann eine der Säuremenge entsprechende Silikatlösung auf die Kohle einwirken, oder tränkt man letztere mit Wasserglaslösung und gibt die entsprechende Menge einer Säurelösung hinzu, so wird in dem getränkten Kohlenkorn Kieselsäure abgeschieden Nach Absaugen von der überschüssigen Lösung erhält man ein Ausgangsmaterial, das neben dem Kohlenstoffskelett audl noch die Struktur des gebildeten Kieselsäuregels aufweist.Production of active carbon containing silicic acid. Addition to patent 453972 It has been found that the process of patent 453 972 leads to a highly active, especially suitable for catalytic purposes, less easily combustible coal in Grain shape in a very simple way, if one of already pre-charred, grained runs out of inactive coal of any origin. If you soak z. B. granulated coal with an acid solution and then leaves a silicate solution corresponding to the amount of acid act on the charcoal, or you soak the latter with water-glass solution and give the appropriate amount of an acid solution is added, so is in the soaked grain of coal Silicic acid deposited. The excess solution is obtained after suction a starting material that, in addition to the carbon skeleton, also has the structure of the Has formed silica gel.

Es ist bereits versucht worden, auf fertiggebildete aktive Kohle Kieselsäuregel niederzuschlagen. Hierbei wird jedoch ein großer Teil der aktiv wirkenden Kohlenoberfläche mit Kieselsäuregel belegt und hierdurch die absorbierend wirkende Kohlenoberfläche beleutend verringert. Da das Absorptionsvermögen der aktiven Kohle im allgemeinen größer ist als das der aktiven Kieselsäure, so wird durch diesen Vorgang die Aktivität des Kohle-Rieselsäuregemisches wesentlich niedriger sein als die Aktivität der reinen Kohle. Attempts have already been made on fully formed active charcoal Precipitate silica gel. Here, however, a large part of the actively acting Carbon surface covered with silica gel and thereby the absorbing effect Coal surface significantly reduced. Because the absorption capacity of the active charcoal is generally greater than that of the active silica, it will be due to this Process the activity of the coal-trickle acid mixture will be significantly lower than the activity of pure coal.

Demgegenüber kann beim Tränken der gewöhnlichen nicht aktiven Holzkohle mit Wasserglas und Abscheiden der Kieselsäure durch nachfolgendes Einwirken von Säure gemäß vorliegender Erfindung eineBedeckung der aktiven Kohlenoberfläche mit Kieselsäuregel nicht eintreten, da diese ja durch die absorptiv gebundenen Teerbestandteile abgesättigt ist. Wird nun eine so vorbereitete inaktive Kohle aktiviert, und zwar nach dem durch Patent geschützten Verfahren, so wird neben dem Kieselsäureskelett ein aktives Kohlengerüst geschaffen, ja es ist sogar anzunehmen, daß die aktive Kohlenoberfläche dadurch vergrößert wird, daß sich Kohlenstoff, herrührend von den Teerbestandteilen, auf dem Kieselsäuregerüst niederschlägt und im weiteren Verlauf des Aktivierungsprozesses selbst in aktive Kohle übergeführt wird. In contrast, when soaking ordinary inactive charcoal with water glass and separation of the silica by subsequent action of Acid according to the present invention has a coverage of the active carbon surface Silica gel does not enter, as this is due to the absorptively bound tar components is saturated. If an inactive coal prepared in this way is activated, namely According to the patented process, it is next to the silica skeleton an active charcoal framework was created, yes it is even to be assumed that the active one Coal surface is increased by the fact that carbon originating from the Tar constituents, precipitates on the silicic acid framework and in the further course the activation process itself is converted into active charcoal.

Durch Veränderung von Glühdauer und Glühtemperatur sowie durch Wahl der Ausgangskörnung kann unter Berücksichtigung der durch den Abbrand bedingten Volumenverkleinerung die Korngröße der erhaltenen aktiven Kohle in beliebigen Grenzen gehalten werden. By changing the annealing duration and temperature as well as by choice the initial grain can, taking into account the burn-off Volume reduction the grain size of the active charcoal obtained can be kept within arbitrary limits.

Die nach dem vorliegenden Verfahren erhaltene Kohle besitzt große mechanische Widerstandsfähigkeit, so daß sie, ohne ihre Körperform zu verlieren, mit besonderem Vorteil für Gasabsorption und katalytische Reaktion zu verwenden ist. The coal obtained by the present process is large in size mechanical resistance so that they can, without losing their body shape, to be used with particular advantage for gas absorption and catalytic reaction is.
