Abstract

The Fe/MgO catalysts prepared from iron nitrate, iron chloride and iron sulfate were studied for catalytic wet oxidation of H₂S to sulfur. They were characterized using BET, XRD, H₂-TPR and TG/DSC techniques. Catalysts prepared from iron nitrate showed the highest H₂S removal ability among the prepared catalysts. Both the TPR and XPS analyses of the catalysts indicate that H₂S removal ability correlates with the dispersion of iron oxide in the Fe/MgO catalysts prepared from different iron precursors.
