Description

Verfahren zur Herstellung von elementarem Schwefel aus iWetallsulfiden und Schwefeldioxyd. Es ist bekannt, elementaren Schwefel zu erzeugen durch Erhitzen vori Schwefelcalcium in einem Strom von Schwefeldioxyd, die Geschwindigkeit dieses Vorganges ist jedoch viel zu gering und die notwendige Reaktionstemperatur zu hoch, um dieses Verfahren technisch verwerten zu können. Außerdem ist die Ausbeute durch die Rückbildung von Gips zu unwirtschaftlich.Process for the production of elemental sulfur from metal sulfides and sulfur dioxide. It is known to produce elemental sulfur by heating before calcium sulfur in a stream of sulfur dioxide, the speed of this However, the process is far too low and the necessary reaction temperature is too high, in order to be able to utilize this process technically. Besides, the yield is through the regression of gypsum too uneconomical.

Es wurde nun gefunden, daß der Schwefel des Schwefeleisens im Schwefeldioxydstrom schon bei 6oo° beginnend mit einer Ausbeute von 7o Prozent und mehr und mit technisch brauchbarer Geschwindigkeit abdestilliert, vermutlich nach der Gleichung: 3 Fe S -f -- 2 SO, - Fei O, -I- 5 S. Benutzt man Pyrit statt Schwefeleisen, so vergrößert sich naturgemäß die Ausbeute an Schwefel.It has now been found that the sulfur of the sulfur iron in the sulfur dioxide stream already distills off at 600 ° with a yield of 70 percent and more and at a technically useful rate, presumably according to the equation: 3 Fe S -f - 2 SO, - Fei O , -I- 5 S. If pyrite is used instead of iron sulfur, the sulfur yield naturally increases.

Auch läßt sich als Ausgangsmaterial anstatt Schwefeleisen ein Gemenge von Sulfaten der Erdalkalien oder des Magnesiumseinerseits, mit metallischem Eisen oder einem seiner niederen Oxyde anderseits, z. B. Gips und Eisenoxydul, oder auch schließlich ein Erdalkalisulfid mit Eisenoxyd, z. B. Schwefelcalcium und Eisenoxyduloxyd, Fei 04 oder Schwefelmagnesium und Eisenoxyd, Fe, 03 verwenden.A mixture can also be used as the starting material instead of sulfur iron of sulphates of alkaline earths or of magnesium on the one hand, with metallic iron or one of its lower oxides on the other hand, e.g. B. plaster of paris and iron oxide, or else finally an alkaline earth sulfide with iron oxide, e.g. B. Calcium Sulfur and Iron Oxide, Use Fei 04 or magnesium sulphide and iron oxide, Fe, 03.

Die jeweils innezuhaltende Temperatur ist abhängig vom Ausgangsprodukt und daher in jedem Falle festzustellen.The temperature to be maintained in each case depends on the starting product and therefore to be determined in each case.
