Description

Herstellung von Schwefelkohlenstoff In der Patentschrift ,184 569 ist ein Verfahren zur Herstellung von Schwefelkohlenstoff aus Kohlenstoff und Schwefelwasserstoff aus Kohledestillationsgasen beschrieben. Es wurde dargelegt, daß die Umsetzung von Schwefelwasserstoff mit glühendem Kohlenstoff ein Gleichgewichtsvorgang ist, und daß man vorteilhaft die Reaktionsgase aus dem Ofen entfernt, wenn höchstens 7o% des Schwefelwasserstoffs in Schwefelkohlenstoff und Wasserstoff umgesetzt sind.Manufacture of Carbon Disulfide In Patent, 184 569 is a process for producing carbon disulfide from carbon and hydrogen sulfide described from coal distillation gases. It was shown that the implementation of Hydrogen sulfide with red-hot carbon is an equilibrium process, and that it is advantageous to remove the reaction gases from the furnace if at most 7o% of the hydrogen sulfide are converted into carbon disulfide and hydrogen.

Die Rückgewinnung des nicht umgesetzten Schwefelwasserstoffs erfolgt nach diesem Verfahren durch Behandlung des Schwefelwasserstoffabgases nach Abscheidung vom gebildeten Schwefelkohlenstoff mittels ammoniakhaltiger Schwefelammonlösung, aus der der Schwefelwasserstoff leicht in konzentrierter Form wieder ausgetrieben und von neuem in den Reaktionsofen eingeführt werden kann. An Stelle von Schwefelammoniumlösung kann man naturgemäß auch andere chemische Absorptionsmittel, wie Sodälösung, oder aber auch feste Adsorptionsmittel verwenden. Man. kann aber auch das den Reaktionsofen verlassende, vom Schwefelkohlenstoff getrennte Gemisch von Wasserstoff und Schwefelwasserstoff wieder mit dem schwefelwasserstoffhaltigen Kohlendestillations-Rohgas vermischen und auf diese Weise die Rückgewinnung des nicht zu Schwefelkohlenstoff umges;etizten Schwefelwasserstoffs gemeinsam mit dien im Gas bereits enthaltenen Schwefelwasserstoff ausführen. Der bei der Umsetzunggewonnene Wasserstoff dient dabei zur Anreicherung des Kohlengases an Wasserstoff.The unconverted hydrogen sulfide is recovered according to this process by treating the hydrogen sulfide off-gas after deposition from the carbon disulfide formed by means of an ammonia-containing sulfur ammonium solution, from which the hydrogen sulfide is easily driven out again in concentrated form and can be reintroduced into the reaction furnace. Instead of sulfur ammonium solution You can of course also use other chemical absorbents, such as soda solution, or but also use solid adsorbents. Man. but can also do the reaction furnace leaving mixture of hydrogen and hydrogen sulfide separated from the carbon disulfide Mix again with the carbon distillation raw gas containing hydrogen sulphide and in this way the recovery of what is not converted to carbon disulfide Hydrogen sulphide together with the hydrogen sulphide already contained in the gas carry out. The hydrogen obtained during the conversion is used for enrichment of the coal gas to hydrogen.
