Abstract

Tungsten oxides based  catalysts on alumina  or  mixed oxide alumina-titania  were  carried out in oxidative  desulfurization (ODS) of dibenzothiophene compounds using H2O2 as oxidant agent. The catalysts were prepared by incipient impregnation method using different loading of tungsten and characterized by x-ray diffraction (XRD), scanning electronic microscopy (SEM-EDX) and  temperature  programmed  reduction (TPR).  The  results  show ODS  activity  was  improved  in  catalysts containing titania and using W species partially reduced.
