Abstract

The effect of molybdena loading on the activity of Mo/MgO catalysts in the H2S wet oxidation at room temperature was studied. The prepared Mo/MgO catalysts were characterized to correlate the physical and structural property of Mo/MgO catalysts with the activity of H2S wet oxidation. No sulfur oxides were detected in the exit gas streams, indicating that the oxidation of H2S to SO2 could be prevented in the wet catalytic oxidation. The Mo/MgO catalysts with below 6 wt % MoO3 maintained the H2S removal efficiency above 99% up to 9 hr. The activity in H2S wet oxidation increased up to 6 wt % MoO3 and then decreased with further increase in molydena loading. The dispersed MgMoO4 phases were active species, while the crystallites of MgMoO4 and Mg2Mo3O11 phases were inactive in H2S wet oxidation.
