| Abstract: | The influences of ultrasonic intensity, H2O2 concentration, ratio of H2O2 to oil and the addition of Fenton reagent on the oxidative desulfurization of diesel oil under ultrasonic irradiation were
investigated. It was observed that the oxidative desulfurization of diesel oil fitted pseudo-first-order kinetics under our
experimental conditions. Increasing the ultrasonic intensity increased the oxidative desulfurization efficiency of diesel
oil. The addition of H2O2 enhanced the ultrasonic oxidative desulfurization efficiency of diesel oil. The sono-oxidation treatment in combination with
Fenton reagent showed a synergistic effect for diesel oil desulfurization. The catalytic oxidative desulfurization process
under ultrasonic irradiation process on diesel oils is an efficient and promising method. |
