Description
Verfahren zur Herstellung eines Gemisches von Schwefelwasserstoff und Schwefeldioxyd. Die Erfindung betrifft ein Verfahren zur Herstellung eines Gemisches von Schwe felwasserstoff und Schwefeldioxyd aus Schwefelerzen als Rohgut.
Dieses Verfahren ist dadurch gekenn zeichnet, dass das Rohgut mit Kohlenstoff gemischt zum Glühen gebracht und einem Strom mit Wasserdampf nicht gesättigter, Sauerstoff enthaltender Gase ausgesetzt wird.
Zur Durchführung des Verfahrens kann vorteilhafterweise Schwefelkies, von belie biger Korngrösse, verwendet werden, welcher mit Brennstoff vom erforderlichen Kohlen stoffgehalt gemischt und zum Beispiel in einem Pyritröstofen geröstet wird. Im Ver laufe der Röstung wird Luft, die durch Wasser von 70 bis 72 C geleitet wurde und daher Wasserdampf enthält, durch die glü hende Schicht geführt.
Es ist dabei zu be achten, dass die zugeführte Luft nicht mit Wasserdampf gesättigt ist, sondern, dass ein Überschuss an Luft bezw. Sauerstoff zu geführt wird, was deshalb notwendig ist, denn sofern die zugeführte Luft mit Wasser gesättigt ist, entsteht nur Schwefelwasser stoff. Schwefelwasserstoff und Schwefel dioxyd reagieren in trockenem Zustand be kanntlich nicht miteinander, so ist es mög lich, beide Gase nebeneinander zu erzeugen, indem man bei dem Durchleiten des Wasser- dampfluftgemisches durch das glühende Roh gut einen entsprechenden Überschuss an Luft vorsieht.
Durch dieses Verfahren erhält man ein Gasgemisch, das je nach dem Schwefel gehalt des verwandten Rohgutes 5 bis 7 Volumenprozente Schv"efelwasserstoff und im Belieben gestellte Mengen Schwefeldioxyd enthält. 2FeSz+2H20+4C+130 = Fe203 -i- 2 HZS -f- 2<B>80,</B> -I- 4 CO#,. Die Reaktion findet in dem glühenden Rohgut statt. Ein Nachheizen ist. meistens nicht notwendig, da die zur Reaktion be nötigte Temperatur ständig bleibt, wenn der Wasserdampfzusatz nicht zu gross ist.
Process for the preparation of a mixture of hydrogen sulfide and sulfur dioxide. The invention relates to a method for producing a mixture of hydrogen sulphide and sulfur dioxide from sulfur ores as raw material.
This process is characterized in that the raw material mixed with carbon is made to glow and is exposed to a stream of water vapor of unsaturated, oxygen-containing gases.
To carry out the process, pebbles of any size can advantageously be used, which is mixed with fuel with the required carbon content and roasted, for example, in a pyrite roasting oven. In the course of roasting, air that has been passed through water at 70 to 72 C and therefore contains water vapor is passed through the glowing layer.
It is important to ensure that the air supplied is not saturated with water vapor, but that an excess of air resp. Oxygen is supplied, which is necessary because if the supplied air is saturated with water, only hydrogen sulfide is produced. It is well known that hydrogen sulphide and sulfur dioxide do not react with one another in the dry state, so it is possible to generate both gases side by side by providing a corresponding excess of air when the water vapor mixture is passed through the glowing raw material.
This process results in a gas mixture which, depending on the sulfur content of the raw material used, contains 5 to 7 percent by volume of hydrogen sulfide and optional amounts of sulfur dioxide. 2FeSz + 2H20 + 4C + 130 = Fe203 -i- 2 HZS -f- 2 <B> 80, </B> -I- 4 CO #,. The reaction takes place in the glowing raw material. Post-heating is usually not necessary, since the temperature required for the reaction remains constant if the addition of steam is not too great is.
