 gebietes mit Hilfe von Kohlenwasserstoffen zu Sulfiden reduziert, und die reduzieren Sulfide mit den kohlensäurehaltigen Abgasen des Reduktionsprozesses unter   Bildung   von Schwefelwasserstoff zersetzt werden. Der gebildete Schwefelwasserstoff kann alsdann in bekannter   Weise für mannigfache   Prozesse. z. B. für die Gewinnung von Schwefel und schwefelsäure, nutzbar gemacht werden. 



   Die beiden Teilvorgänge, aus denen sich das Verfahren zusammensetzt, nämlich die Reduktion von Sulfaten zu Sulfiden und die Zersetzung von Sulfiden mittels kohlensäurehaltiger Gase sind an sich 
 EMI1.2 
 zu gewinnen ; hier weist erst das vorliegende Verfahren die Wege. 



   Zunächst ist es   selbstverständlich notwendig, dass   die zu reduzierenden Sulfate mögliehst rein sind. und dass das für die Reduktion dienende Gas keine, oder keine irgendwie erheblichen Mengen störender Verunreinigungen, wie Halogene, Halogenverbindungen, Schwefeldixyd oder auch Saueitsoff enthält. Daher können für das vorliegende Verfahren ungereinigte Destillationsgase irgendwelcher Art nicht in Frage kommen ; gut geeignet sind dagegen gereinigte Gase und vor allem reine   Naturgase.   wie sie im Erdgas als fast reines Methan vielfach zur Verfugung stellen. 



   Für das Arbeitsverfahren selbst ist die   Wal) ! des Temperaturgebietes massgebend, denn   es muss

 unerwünschter Zersetzungsprodukte aus den sulfaten vermieden werden. 



   Es ist erkannt worden. dass diese Forderungen sich erfüllen lassen, wenn die Reduktion in einem ziemlich eng begrenzten   Temperaturgebiet vorgenommen   wird, das für die   hauptsächlich   in Frage kommenden Reduktionsmittel praktisch zwischen 850  und 1050  liegt. Arbeitet man bei wesentlich niedrigerer Temperatur, so erhalten die Gase unverbrauchte Reduktionsmittel : steigt die   Temperatur   erheblich über die angegebene Höchstgrenze hinaus, so bilden sich Sauerstoffverbindungen des Schwefels, vor allen   schweflige   Säure. 



   Nun ist aber das eine so   unerwünscht   wie das andere, denn   sowohl nnverbtauchte Reduktionsgase.

 area is reduced to sulphides with the help of hydrocarbons, and the reduced sulphides are decomposed with the carbonated exhaust gases of the reduction process to form hydrogen sulphide. The hydrogen sulphide formed can then be used in a known manner for a variety of processes. z. B. for the extraction of sulfur and sulfuric acid, can be made usable.



   The two sub-processes that make up the process, namely the reduction of sulfates to sulfides and the decomposition of sulfides by means of carbonated gases, are in themselves

 to win ; here only the present proceedings point the way.



   First of all it is of course necessary that the sulfates to be reduced are as pure as possible. and that the gas used for the reduction does not contain any or any significant amounts of interfering impurities such as halogens, halogen compounds, sulfur dioxide or even oxygen. Therefore, unpurified distillation gases of any kind cannot be considered for the present process; In contrast, purified gases and, above all, pure natural gases are well suited. as they are often available in natural gas as almost pure methane.



   For the working process itself is the whale)! of the temperature range is decisive, because it must

 unwanted decomposition products from the sulfates can be avoided.



   It has been recognized. that these requirements can be met if the reduction is carried out in a rather narrowly limited temperature range, which is practically between 850 and 1050 for the reducing agents mainly in question. If you work at a much lower temperature, the gases contain unused reducing agents: if the temperature rises significantly above the specified maximum limit, sulfur oxygen compounds are formed, especially sulfurous acid.



   But now one is as undesirable as the other, because both non-consumed reducing gases.
