Abstract: (118 Views)

Ultrasonic desulfurization of commercial naphtha was performed by different catalysts, such as acetic acid, formic acid, FeSO₄, phosphotangestic acid, and hydrogen peroxide as oxidant by ultrasound-assisted oxidative desulfurization (UAOD) process. The factors studied were time, temperature, and the type of catalyst with the aim of being applied on an industrial scale. The results indicated the high capacity of this process for commercial naphtha desulfurization. Furthermore, the best results were observed for acetic acid and formic acid, and sulfur content reduced from 2890 ppm to 28 ppm and 55 ppm, respectively. The removal of sulfur is enhanced by a decline in temperature and an increase in time.
