Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 50 N° 18 (Septembre 2011) . - pp. 10452–10457 Titre : Oxidative desulfurization II : temperature dependence of organosulfur compounds oxidation Type de document : texte imprimé Auteurs : Paolo De Filippis, Auteur ; Giuseppe Liuzzo, Auteur ; Marco Scarsella, Auteur Année de publication : 2011 Article en page(s) : pp. 10452–10457 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Temperature effect Desulfurization Oxidation 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.
