PROCESS FOR THE REMOVAL OF HYDROGEN SULFIDE, BY MEANS OF ITS OXIDATION IN THE PRESENCE OF HETERO POLYACIDS
摘要
Hydrogen sulfide is oxidized to sulfur by means of treatment with an aqueous acid solution containing trivalent iron and a hetero polyacid having formula (I): H<SUB>n</SUB> X V<SUB>y</SUB> M<SUB>(12-y)</SUB> O<SUB>40</SUB>; or a sole hetero polyacid having formula (II): H<SUB>n</SUB> Me M<SUB>12</SUB> O<SUB>40</SUB>; wherein the symbols X, M Me n and y are specified in the text. At the end of the oxidation, the solution is treated with gas containing oxygen to re-oxidize the reduced metal.
