| Résumé : | Oxidative desulfurization routes appear among the most promising methods for obtaining ultralow-sulfur diesel fuels requested worldwide by environmental legislation. In this work, the oxidation kinetic of benzo- and dibenzothiophene with the oxidizing system constituted by hydrogen peroxide and formic acid was studied in isothermal conditions at 40 °C. Since the oxidation occurs in a heterophasic system, both physical and chemical phenomena play an important rule. The aim of this work was to interpret the obtained experimental conversions with a model able to capture the influence of both mass transfer and chemical kinetics. The results allowed verification that the oxidation reaction occurs in the slow liquid−liquid reaction regime and chemical kinetics is the controlling step. The identified values of the intrinsic kinetic constants for the oxidation of benzo- and dibenzothiophene are 2.255 × 10−1 and 1.206 × 100 m3 kmol−1 s−1, respectively. |
