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>XV<SUB>y</SUB>M<SUB>(12-y)</SUB>O<SUB>40</SUB>; or a sole hetero polyacid having formula (II): H<SUB>n</SUB>MeM<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.
