| Résumé : | In this work the oxidation of benzo-, dibenzo-, 4-methyldibenzo-, and 4,6-dimethyildibenzothiophene in the presence of hydrogen peroxide and formic acid was studied over the temperature range of 20―65 °C. The experimental data were interpreted by means of a interfacial mass transfer and reaction model developed in the first part of this study. The parameters identification tool available in gPROMS environment allowed a regression of the Arrhenius constants of the rate determining step characterizing the considered oxidation reactions. The activation energies of the thiophenes oxidation reactions result in 34.6 kJ/mol and 29 ± 1 kJ/mol for BT and DBTs, respectively. |
