Description
Zerreiben von aktiver Kohle ohne Verlust an Aktivität Gegenstand der Erfindung ist ein Verfahren zum Zerreiben von aktiver Kohle ohne Verlust an Aktivität, das dadurch gekennzeichnet ist, daß die Zerreibung oder Pulverisierung in irgendeiner Flüssigkeit, die vorzugsweise eine große Kapillarspannung besitzt, vorgenommen wird, um eine Verstopfung der Poren der Kohle und ein Zerdrücken der Kanäle auf der Oberfläche zu vermeiden.The object of grinding active charcoal without loss of activity Invention is a method for grinding active charcoal without loss of activity, which is characterized in that the attrition or pulverization in any Liquid, which preferably has a high capillary tension, is carried out, clogging the pores of the coal and crushing the channels on the surface to avoid.
Für verschiedene Zwecke, z. B. bei der Weinbereitung, in der Ölindustrie oder al,-Gasschutzkohle, verwendet man Kohle pulverförmig .oder gestoßen von einem ganz-- bestimmten Feinheitsgrad. Man muß also, da es bei einem guten, regelmäßigen Fabrikationsbetrieb fast unumgänglich ist, die Masse zu agglomerieren oder in Bruchstücke bestimmter Größe zu teilen, später die Kohle pulvern oder zerreiben.For various purposes, e.g. B. in winemaking, in the oil industry or al, gas protective carbon, one uses coal in powder form. or pushed by one very specific degree of fineness. So you have to, since it is a good, regular one Manufacturing operation is almost inevitable to agglomerate the mass or into fragments To divide a certain size, later powder or grind the charcoal.
Dabei macht man die Beobachtung, daß durch diese Behandlung die Aktivität der gewöhnlichen Kohle beträchtlich leidet.It is observed that this treatment increases the activity the common coal suffers considerably.
Untersuchungen haben ergeben, daß der Verlust an Aktivität durch das Verstopfen der Poren der Kohle durch den bei der Zerreibung entstehenden feinen Staub, in geringerem Maße durch das Zerdrücken der Kanäle auf der Oberfläche der Stücke verursacht wird.Research has shown that the loss of activity due to the Clogging of the pores of the charcoal due to the fine particles produced by the attrition Dust, to a lesser extent, by crushing the channels on the surface of the Pieces is caused.
Um eine Abnahme der Aktivität zu vermeiden, muß man das Zerreiben der Kohle in einer Flüssigkeit von einer genügend starken Kapillarspannung vornehmen. Diese Flüssigkeit -wird hauptsächlich Wasser sein, aber man kann, je nach dem Falle, auch Öle oder Kohlenwasserstoffe verwenden. Ist die angewandte Flüssigkeit flüchtig, so kann man die Kohle trocknen und findet dann, daß nach der Zerreibung die Kohle fast die gleiche Aktivität wie früher besitzt.To avoid a decrease in activity, one must grind the carbon in a liquid with a sufficiently strong capillary tension. This liquid will mainly be water, but one can, depending on the case, also use oils or hydrocarbons. If the applied liquid is volatile, in this way one can dry the charcoal and then find that after the attrition the charcoal has almost the same activity as before.
In manchen Fällen empfiehlt ies sich, im Vakuum zu trocknen, um die Trocknungstemperatur niedrig zu halten. Jedenfalls braucht man die Kohle nicht zu trocknen, sondern kann sie trocken oder mit Flüssigkeit getränkt gebrauchen, besonders wenn man mit Entfärbungskohlenpaste, -wie z. B. bei der Weinbereitung, arbeiten -will.In some cases it is advisable to dry in a vacuum in order to remove the Keep drying temperature low. In any case, you don't need the coal dry, but can use them dry or soaked in liquid, especially if you use decolorizing carbon paste, -like z. B. in winemaking, work -want.
