Description

Aktivierung von Kohle unter gleichzeitiger Gewinnung von Schwefelkohlenstoff Es wurde gefunden, daß beim Behandeln von Kohle oder Kohlenstoff enthaltenden Stoffen mit Schwefeldämpfen oder schwefelabspaltenden Stoffen bei erhöhter Temperatur, beispielsweise bei 8oo bis iooo°, eine Aktivierung der Kohle unter gleichzeitiger Bildung von Schwefelkohlenstoff eintritt. Die Kohle wird so lange dieser Behandlung ausgesetzt, bis sie aktiveEigenschaften angenommen hat. Wenn dies eingetreten ist, wird der Prozeß unterbrochen. Durch passende Wahl der Ausgangskohle, ihrer Korngröße, der Temperatur, der Dauer der Schwefeleinwirkung und der Konzentration der Schwefeldämpfe, welche beispielsweise durch inerte Gase oder Dämpfe wie Stickstoff, Schwefelkohlenstoff o. a. variiert werden kann, hat man es in der Hand, aktive Kohlen bestimmter Eigenschaften zu erzielen. Behandelt man beispielsweise 24 Gewichtsteile bei 500° verkoktes Fichtenholz mit Schwefeldämpfen bei goo° so lange, bis sich etwa 76 Gewichtsteile Schwefelkohlenstoff gebildet haben, so erhält man etwa 12 Gewichtsteile einer guten Entfärbungskohle vom Litergewicht ioo bis 2oo g; treibt man die Aktivierung weiter, so kann man Kohlen erzielen, welche im Entfärbungsvermögen hochaktiven Wasserdampfkohlen gleichkommen. Zweckmäßig verbindet man die Aktivierung der Kohlen mit einer Schwefelkohlenstoffgewinnung. Je nach Umständen läßt sich der ganze Prozeß in Retorten mit Außenbeheizung oder in Apparaten mit elektrischer Widerstandsheizung ausführen oder es läßt sich schließlich die für die Umsetzung C+ SZ = CS2 erforderliche Wärmemenge durch Überhitzung der Schwefeldämpfe zuführen. Der Prozeß läßt sich sowohl diskontinuierlich oder kontinuierlich unter Bewegung der Kohle, beispielsweise in geeignet konstruierten Schacht- oder Drehöfen, ausführen.Activation of coal with simultaneous production of carbon disulfide It has been found that when treating coal or carbon-containing substances with sulfur vapors or sulfur-releasing substances at elevated temperatures, for example at 8oo to 100o °, an activation of the carbon with simultaneous formation of carbon disulfide entry. The carbon is subjected to this treatment until it has active properties has accepted. When this occurs, the process is interrupted. By matching Choice of the starting coal, its grain size, the temperature, the duration of the sulfur exposure and the concentration of sulfur vapors, which can be caused, for example, by inert gases or vapors such as nitrogen, carbon disulfide or the like. can be varied, has it is in hand to obtain active coals of certain properties. Treated for example, 24 parts by weight of spruce wood coked at 500 ° with sulfur vapors at goo ° until about 76 parts by weight of carbon disulfide have formed, this gives about 12 parts by weight of good decolorizing charcoal weighing a liter 100 to 200 g; if one drives the activation further, one can achieve coals, which are equivalent to highly active steam carbons in their decolorizing capacity. Conveniently connects one activates the coals with a carbon disulfide production. Depending on the circumstances the whole process can be carried out in retorts with external heating or in apparatus run electrical resistance heating or it can finally be used for the implementation C + SZ = CS2 required amount of heat by overheating the sulfur vapors respectively. The process can be either discontinuous or continuous Moving the coal, for example in suitably constructed shaft or rotary kilns, carry out.
