Ultrasound-Assisted Oxidative Desulfurization Process of Gas Oil

The ultrasound-assisted oxidative desulfurization process was used for gas oil sulfur removal. The effective factors such as reaction time (5 and 10minutes), temperature (8-65°C), type of extraction solvent and catalyst in present of ultrasonic irradiation (400 W and 24 kHz) were considered fordecreasing the amount of sulfur. In this study, the highest removal was achieved during 10 minutes of process at 65°C when extraction was done bymethanol. In this work, two phases was separated and ASTM 3120 method was used for analyzing oil phase.
