    Abstract: In this research, a process system optimization in the ultrasound assisted oxidative desulfurization (UAOD) with the NaPW/H2O2 system was investigated to determine its sustainability to produce clean diesel. The UAOD process was used to identify the effect of sulfur conversion with ultrasound time (6 to 30 min), amplitude (20 to 60%), catalyst dosage (10 to 500 mg), and temperature (30 to 70 degrees C). Results showed that the variables of amplitude, catalyst dosage, and temperature were extremely significant (p-value < 0.0001). Strong statistical significance (p-value < 0.0001 and F-value = 24.8) has been displayed for the generated model. The optimum sulfur conversion of 99.6% (theoretical) and 95.0% (verified) in diesel was attained at 27.1 min, 39.9% amplitude, 320.9 mg catalyst, and 69.7 degrees C. Thus, the results of this study indicated the novel applicability of the UAOD as a desulfurization technology in industrial practice.
