Title
CO methanation over supported Mo catalysts in the presence of H2S
Abstract

The effect of various Mo catalyst supports, i.e., γ-Al2O3, SiO2, SiO2–Al2O3, ZrO2, yttria-stabilized zirconia (YSZ), CeO2, and TiO2, on CO hydrogenation in the presence of H2S was examined. At 5 wt.% Mo loading, Mo/ZrO2 was determined to be the most active catalyst for this reaction; its activity was dependent on the number of active sites, as determined via NO chemisorption. Raman spectroscopy revealed that MoO3 transforms into MoS2 during the reaction.
