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 °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 °C. Thus, the results of this study indicated the novel applicability of the UAOD as a desulfurization technology in industrial practice.

_{在本研究中，研究了采用 NaPW/H 2} O ₂系统的超声辅助氧化脱硫 (UAOD) 中的工艺系统优化，以确定其生产清洁柴油的可持续性。UAOD 工艺用于确定硫转化对超声时间（6 至 30 分钟）、振幅（20 至 60%）、催化剂用量（10 至 500 毫克）和温度（30 至 70 °C）的影响。结果表明，振幅、催化剂用量和温度的变量非常显着（p值<0.0001）。强统计显着性（p 值 < 0.0001 和F 值 = 24.8) 已为生成的模型显示。在 27.1 min、39.9% 振幅、320.9 mg 催化剂和 69.7 °C 时，柴油中的最佳硫转化率为 99.6%（理论值）和 95.0%（验证）。因此，本研究结果表明 UAOD 作为脱硫技术在工业实践中的新颖适用性。
