Oxidative desulfurization of dibenzothiophenes using VOx/ZrO2-Al2O3
M.A. Alvarez-Amparán and L. Cedeño-Caero
-
Catalysts with different V loading and different oxidation degrees were prepared on a zirconia-alumina mixed oxide.
The catalytic activity of VOx catalysts was tested in oxidative desulfurization process (ODS).
It was used tert-butyl hydroperoxide (TBHP) and hydrogen peroxide as oxidant agents.
Reduced vanadium species presented greater reactivity with TBHP, while oxidized vanadium with H2O2.
