Abstract: Several transition metal (Cu²⁺, Fe³⁺, Zn²⁺, Mn⁴⁺, and Cr⁶⁺) salts of H₄PMo₁₁VO₄₀ were prepared and their solutions were used initially for H₂S removal in the liquid redox process. H₂S removal tests were performed by dynamic absorption experiments. Among these polyoxometalates, that with the Cu²⁺ cation was found to have pronounced H₂S removal performance with the removal efficiency of up to 98%. The relevant oxidative desulfurization mechanism and the role of Cu²⁺ were studied.

Keywords: H₂S; Desulfurization; Liquid redox; Polyoxometalate
