In this work, the effect of microwave irradiation on the catalytic oxidative desulfurization (ODS) of light gasoil fraction has been investigated using core/shell magnetic silica supported with phosphotungstic acid ([email protected]\PWA) nanocomposite catalyst. Different experimental parameters including catalyst amount, H₂O₂:gasoil ratio, as well as microwave irradiation power and exposure time have been studied. [email protected]\PWA nanocomposite exhibited high desulfurization efficiency (ca. 94.5%) under suitable conditions of microwave-induced catalytic ODS in short reaction times. The catalyst recyclability study showed that the prepared catalyst can be magnetically separated and reused at least six times with an unimportant loss of its activity.

在这项工作中，已经研究了使用磷钨酸（[电子邮件保护] \ PWA）纳米复合催化剂负载的核/壳磁性二氧化硅对微波辐照对轻柴油馏分的催化氧化脱硫（ODS）的影响。研究了不同的实验参数，包括催化剂用量，H ₂ O ₂：汽油比，微波辐射功率和暴露时间。受电子邮件保护的\ PWA纳米复合材料在微波诱导的催化ODS的合适条件下，以较短的反应时间表现出较高的脱硫效率（约94.5％）。催化剂的可循环性研究表明，所制备的催化剂可以进行磁分离并重复使用至少六次，而活性的损失并不重要。
