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, V-51 NMR, H-2-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 6 wt.%. This superior catalytic performance might be related to the uniform dispersion of vanadia species on the Al-PILC support. (C) 2012 Elsevier B.V. All rights reserved.
