Description

Herstellung von Schwefelkohlenstoff Es wurde gefunden, daß man die Umsetzung erhitzten kohlenstoffhaltigen Materials mit Schwefeldämpfen zu Schwefelkohlenstoff katalytisch beeinflussen kann, wenn man dem kohlenstoffhaltigen Material geringe Mengen von Kupferverbindungen, z. B. Kupferoxyd oder nichtflüchtige Kupfersalze, zusetzt. Durch solche Zusätze wird die Umsetzungstemperatur des kohlenstoffhaltigen Materials mit den Schwefeldämpfen beachtlich herabgesetzt.Production of carbon disulfide It has been found that the Conversion of heated carbonaceous material with sulfur fumes to carbon disulfide can affect catalytically if you give the carbonaceous material low Amounts of copper compounds, e.g. B. copper oxide or non-volatile copper salts, clogs. Such additives increase the reaction temperature of the carbonaceous Material with the sulfur vapors is considerably reduced.

Die Beimischung der Kupferverbindung zum kohlenstoffhaltigen Material geschieht zweckmäßig in der Weise, daß man das kdhl!enstoffhaltige Material mit einer etwa o, i %igen Kupfersalzlösung tränkt und sodann trocknet. Die Trocknung kann .auch im Reaktionsofen selbst erfolgen, bevor der Schwefeldampf zur Einwirkung gebracht wird.The addition of the copper compound to the carbonaceous material is expediently done in such a way that the coolant-containing material is also used an approximately o, i% copper salt solution soaks and then dries. The drying can also take place in the reaction furnace itself before the sulfur vapor takes effect is brought.

Beispiel i ioo Gewichtsteile einer durch Schwelung von Lignin hergestellten Kohle mit der Körnung i bis 6 mm werden mit i oo Gewichtsteilen einer o, I o/oigen Kupfernitratlösung getränkt und sodann bei 12o° getrocknet. Während nichtvorbehandelte Ligninkohle in der gleichen Apparatur erst bei 68o° mit Schwefeldampf reagiert, erfolgt die Umsetzung der vorbehandelten Kohle bereits bei 65o°.Example 100 parts by weight of one produced by carbonisation of lignin Coal with a grain size of 1 to 6 mm are given 10 parts by weight of an o, 10% Soaked copper nitrate solution and then dried at 120 °. While not pretreated Lignin charcoal only reacts with sulfur vapor at 68o ° in the same apparatus, the conversion of the pretreated coal takes place at 65o °.

Beispiel 2 ioo Gewichtsteile geschwelte Braunkohlenbriketts (Körnung i bis 6 mm) werden, wie in Beispiel i beschrieben, mit einer Kupfersalzlösung vorbehandelt. Die Umsetzung mit Schwefeldimpfen erfolgt bei-diesem Material bei 69o°, während nichtvorbehandelter Schwelkoks erst bei -72o° reagiert.Example 2 100 parts by weight of smoked lignite briquettes (grain size i to 6 mm) are, as described in example i, pretreated with a copper salt solution. The reaction with sulfur inoculation takes place with this material at 69o °, while non-pretreated coke only reacts at -72o °.
