Description
Es ist ein Verfahren zur Darstellung von Schwefel durch Einwirkung von Schwefeldioxyd auf Kohlenstoff in der Hitze in Gegenwart von Metallverbindungen bekannt. Dieses Verfahren ist dadurch gekennzeichnet, daß Schwefeldioxyd enthaltende Gase mit einem kohlenstoffhaltigen Reduktionsmittel, insbesondere Kohle, in Gegenwart eines basischen Stoffes, der ein sehr schwer schmelzbares Sulfid bildet, behandelt werden.It is a process for the preparation of sulfur through the action of sulfur dioxide known on carbon in the heat in the presence of metal compounds. This method is characterized in that gases containing sulfur dioxide with a carbon-containing Reducing agent, especially coal, in the presence of a basic substance, which is very difficult forms fusible sulphide.
ίο Zur Durchführung des Verfahrens soll nach den darüber vorliegenden Angaben in der Weise verfahren werden, daß die schwefeldioxydhaltigen Gase, unter Beheizung von außen, mit Kohle in Gegenwart von Schwefelcalcium oder einer anderen Kalkverbindung umgesetzt werden.ίο To carry out the procedure, according to the information available about it are proceeded in such a way that the sulfur dioxide-containing Gases, with external heating, with coal in the presence of calcium sulfur or another lime compound.
Eine praktische Bedeutung hat dieses Verfahren jedoch nicht erlangt, vornehmlich deshalb, weil durch die Beheizung von außen einerseits ein großer Wärmeverlust entsteht, und andererseits eine gleichmäßige Durchheizung der Masse kaum zu erzielen ist.However, this process has not achieved any practical significance, primarily because because the heating from the outside results in a large loss of heat on the one hand, and even heating through on the other the mass can hardly be achieved.
Es -wurde nun gefunden, daß diese Nachteile vermieden werden und daß man eine glatte Umsetzung des Schwefeldioxyds in Schwefel dadurch erreichen kann, daß man die hierzu erforderliche Temperatur nicht durch Beheizung von außen, sondern innerhalb des Reaktionsraumes selbst erzeugt. Man erreicht dies z.B. It has now been found that these disadvantages are avoided and that one smooth conversion of the sulfur dioxide into sulfur can be achieved by the fact that this required temperature is not generated by heating from the outside, but within the reaction chamber itself. This can be achieved e.g.
dadurch, daß man dem schwefeldioxydhaltigen Gasgemisch soviel Luft zufügt, daß durch die Verbrennung der Kohle mit dem Sauerstoff die erforderliche Temperatur zustande kommt.by adding so much air to the gas mixture containing sulfur dioxide that through the Combustion of the coal with the oxygen the required temperature comes about.
So ist man in der Lage, die ganze Reaktion in der einfachsten Weise in einem Schachtofen, Generator o. dgl., auszuführen.So one is able to carry out the whole reaction in the simplest way in a shaft furnace, Generator or the like.
Da die den Reaktionsraum verlassenden Gase neben freiem Schwefel noch flüchtige Schwefelverbindungen, wie Kohlenstoffoxysulfid und Schwefelwasserstoff, enthalten, so leitet man die noch heißen Gase über Gips, der die genannten Verbindungen zu Kohlendioxyd, Wasser und Schwefel neben geringen Mengen Schwefeldioxyd oxydiert und dabei selbst in Schwefelcalcium übergeht. Mit Rücksicht darauf, daß die hierzu nötige Temperatur im Ofen vorhanden ist, setzt man die erforderliche Menge Gips zweckmäßig gleich der Kohle im Schachtofen zu.Since the gases leaving the reaction space not only contain free sulfur but also volatile sulfur compounds, such as carbon oxysulphide and hydrogen sulphide, so one derives the still hot gases via plaster of paris, which the compounds mentioned to carbon dioxide, water and sulfur, along with small amounts of sulfur dioxide, is oxidized, and in so doing itself into calcium sulfur transforms. With regard to the fact that the temperature required for this is available in the oven the required amount of gypsum is expediently equal to the coal in the shaft furnace to.
Durch diese Maßnahmen erreicht man noch, daß ein großer Teil des Schwefels im Gips, der in den heißeren Zonen des Ofens als schweflige Säure in Freiheit gesetzt wird, am Schluß als Schwefel gewonnen wird.With these measures one still achieves that a large part of the sulfur in the gypsum, which is released as sulphurous acid in the hotter zones of the furnace, at the end is obtained as sulfur.
Das Ausbringen des Schwefels aus dem Gips kann durch Zugabe von Substanzen, wie Eisenoxyd, Aluminiumoxyd, Ton, Granit, Quarzporphyr u. dgl., verbessert werden. Es ist zweckmäßig, die Zuschläge derart zu bemessen, daß eine leicht schmelzbare Schlacke entsteht, wodurch der Durchsatz erhöht und der Betrieb vereinfacht wird.The sulfur can be extracted from the gypsum by adding substances such as iron oxide, Alumina, clay, granite, quartz porphyry and the like can be improved. It is advisable to measure the surcharges in such a way that that an easily meltable slag is formed, whereby the throughput increases and the operation is simplified.
Das vorliegende Verfahren bietet infolge fortfallender Außenbeheizung den Vorteil einer vollkommenen Ausnutzung der Wärme und einer wesentlichen Vereinfachung in der Apparatur.The present procedure offers as a result of omitted External heating has the advantage of making full use of the heat and a significant simplification of the apparatus.
