Bisher konnte Schwefelwasserstoff durch Ferrisalze nur zu Schwefel oxydiert werden. Es hat sich jedoch gezeigt, daß wider Erwarten beim Einleiten schwefelwasserstoffhaltiger Gase in eine heiße, zweckmäßig stark schwefelsaure Ferrisulfatlösung, wenn abwechselnd oder gleichzeitig die Regeneration des gebildeten Ferrosulfates durch Luft oder Sauerstoff erfolgt, eine Oxydation zu SchwefelsäureSo far, hydrogen sulfide could only be oxidized to sulfur by ferric salts. However, it has been shown that, contrary to expectations, when introducing hydrogen sulfide-containing Gases in a hot, expediently strong sulfuric acid ferric sulfate solution, if alternately or at the same time the regeneration of the ferrous sulphate formed by air or oxygen occurs, an oxidation to sulfuric acid
ίο ohne Abscheidung von Schwefel stattfindet. Durch Einblasen von Luft oder Sauerstoff oder Oxydation auf andere Art wird das Ferrisulfat wieder regeneriert, und der primär ausgeschiedene Schwefel wird in der Wärme in der Schwefelsäure unter deren teilweiser Reduktion zu schwefliger Säure gelöst nach der Gleichungίο takes place without separation of sulfur. The ferric sulphate is made by blowing in air or oxygen or by oxidation in some other way regenerated again, and the primarily separated sulfur is in the heat in the sulfuric acid with its partial reduction to sulphurous acid solved according to the equation
2 (H2 S O4) + S + H2 O = 3 (H2 S O3).2 (H 2 SO 4 ) + S + H 2 O = 3 (H 2 SO 3 ).
Die schweflige Säure reduziert wieder das Ferri-Ion und wird dabei selbst zu Schwefelsäure oxydiert. Selbstverständlich gehen die beiden Reaktionen nebeneinander vor sich, und auch die Regeneration erfolgt nicht zeitlich verschieden. Die hierdurch gewonnene Schwefelsäure ist eisenhaltig und. kann entweder als solche verwendet oder zur Ammoniakbindung herangezogen werden, wobei man, wenn der Neutralisationspunkt erreicht ist, das nunmehr bestehen bleibende Eisensulfid vom Ammoniumsulfat trennen kann. Die Regeneration des Eisensulfides erfolgt durch neuerliches Aufgeben in die Oxydationslösung. The sulphurous acid reduces the ferric ion again and becomes sulfuric acid itself oxidized. Of course, the two reactions take place side by side, and the regeneration does not differ in time either. The resulting Sulfuric acid is ferrous and. can either be used as such or to bind ammonia can be used, with one when the neutralization point is reached is, the now existing iron sulfide can separate from the ammonium sulfate. The iron sulfide is regenerated by adding it again to the oxidation solution.
