About the Book

La présence de soufre dans le pétrole brut lourd a posé d'énormes défis quant à ses impacts négatifs sur l'environnement et l'économie. Dans cette étude, la désulfuration par oxydation-extraction du pétrole brut lourd a été réalisée avec le réactif de Fenton, KMnO4, et KMnO4+H2O2 comme oxydants sur un catalyseur d'acide acétique et formique à différents systèmes d'oxydation/catalyseur, à une température de 60 et 80 ˚C respectivement et la pression dans la réaction était atmosphérique. Après la réaction d'oxydation, l'huile oxydée a été extraite avec du DMSO pour la séparation du sulfoxyde. L'huile désulfurée a été analysée en utilisant l'analyseur de soufre dans l'huile XRF et l'analyse spectrophotométrique FT-IR. La désulfuration la plus élevée a été obtenue à la température d'oxydation de 60 ˚C pendant 15 minutes avec un système d'oxydation KMnO4+H2O2/HCOOH oxydant/catalyseur, la désulfuration de 73,00% a été obtenue. Les différents tests de réaction d'oxydation ont montré que l'augmentation de la température de réaction augmentait légèrement la désulfuration. La combinaison KMnO4/H2O2 était meilleure que Fe2+/H2O2 (réactif de Fenton) comme oxydant du soufre organique en présence de HCOOH comme catalyseur. Cependant, le DMSO s'est avéré être un mauvais solvant pour l'extraction du soufre oxydé.
