ABSTRACT:
An aqueous catalytic oxidation-reduction composition for oxidizing hydrogen sulfide to produce elemental sulfur and a method of removing hydrogen sulfide from a gas stream whereby a gas stream containing hydrogen sulfide is brought into contact with an aqueous catalytic oxidizing reaction composition containing a water soluble polyvalent metal salt having the metal in the higher valent state and at least one surfactant, preferably a low foaming nonionic surfactant, such as a linear alcohol alkoxylate surfactant, which is adapted to wet the elemental sulfur formed and having the surfactant present in the reaction solution in an amount sufficient to prevent formation of sulfur froth on the surface of the reaction solution.
