The Mo/MgO catalysts with different MoO 3 loadings were prepared by impregnating MgO support with aqueous ammonium heptamolybdate solution. The highest removal capacity of H 2S was obtained with a molybdenum content of 6 wt %, which was almost close to the theoretical monolayer capacity on MgO support. The surface coverage calculation of MoO 3 suggested that a molybdenum oxide addition up to a monomolecular layer on MgO support increased the H 2S removal capacity of Mo/MgO, but the further increase of Mo-O surface coverage decreased that. Small domains of MgMoO 4 could be present on Mo/MgO with molybdena loadings below 6 wt %. This is an abstract of a paper presented at the 227th ACS National Meeting (Anaheim, CA 3/28/2004-4/1/2004).
