Oxidative desulfurization of diesel fuel oil using supported Fenton catalysts and assisted with ultrasonic energy
Abstract An ultrasound-assisted heterogeneous catalytic oxidation process was applied to eliminate sulfur from commercial diesel fuel oil. The studied variables were catalyst concentration, type of catalyst (homogeneous or heterogeneous), oxidizing agent concentration, and the application of ultraso...
