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.
