Catalytic performance of vanadia-doped alumina-pillared clay for selective oxidation of H2S
Abstract The catalytic oxidation of hydrogen sulfide over V2O5 supported on Al-pillared clay (V/Al-PILCs) was studied. The synthesized catalysts were examined using a variety of characterization techniques such as XRD, BET, XPS, 51V NMR, H2-TPR and NH3-TPD. A catalytic activity study performed by using V/Al-PILC catalysts showed that H2S was successfully converted to elemental sulfur without considerable emission of sulfur dioxide. The H2S conversion over V/Al-PILCs increased with the vanadia content up to 6wt.%. This superior catalytic performance might be related to the uniform dispersion of vanadia species on the Al-PILC support.
Graphical abstract Display Omitted Highlights ► Novel layered vanadia-supported alumina-pillared clays (V/Al-PILCs) were prepared. ► They were used as catalysts for the selective oxidation of H2S to elemental sulfur. ► They showed very high catalytic activity even in the presence of water vapor.
