Deep Oxidative Desulfurization of Model Fuel with H₂O₂ Catalyzed by Ce-Mo/SiO₂ Catalysts

Abstract:

The catalysts of HPMo/SiO2 modified with Ce3+ were prepared by the sol-gel method. The catalysts were characterized by FT-IR, XRD, SEM and pore structure parameters and evaluated for the oxidative desulfurization of model fuel using hydrogen peroxide as an oxidant. Results showed that the catalysts kept the Keggin structures and the introduction of CeCl3 promoted the high dispersion of MoO3 over SiO2 and increased the specific surface area of the catalysts. Under the optimal reaction conditions, the desulfurization rate for dibenzothiophene (DBT) and benzothiophene (BT) achieved 98.9% and 43.4%, respectively.
