Selective Oxidation of H2S to Ammonium Thiosulfate and Elemental Sulfur Using Mixtures of V-Bi-O and Sb2O4
Kim BK, Hwang BH, Lee HS, Woo HC, Park DW
The selective oxidation of hydrogen sulfide in the presence of excess water and ammonia was investigated by using vanadium-bismuth based mixed oxide catalysts. Synergistic effect on catalytic activity was observed for the mechanical mixtures of V-Bi-O and Sb2O4. Temperature programmed oxidation (TPO), X-ray photoelectron spectroscopy (XPS), and two separated bed reactivity test results supported the role of Sb2O4 for reoxidizing the reduced VBi-O during the reaction.
Keywords: H2S; Selective Oxidation; Ammonium Thiosulfate; V-Bi-O; Sb2O4
