Batch oxidative desulfurization of model light gasoil over bimetallic nanocatalyst

This work explored the design and synthesis of a novel AgO/ZnO/HY-Zeolite bimetallic nanocatalyst by an impregnation method. The purpose of this nanocatalyst was to remove the dibenzothiophene as the primary sulfur content from a light gasoil model via a catalytic oxidative desulfurization process (ODS). The characteristics of the synthesized nanocatalyst were determined by FTIR, BET, SEM, and XRD. The synthesized nanocatalyst indicated an area of 252 m2g-1, pore volume and pore size equal to 0.221 cm3g-1 and 2.15 Ao, respectively. The ODS results revealed better sulfur conversion i.e. 91.8% conversion efficiency at optimal ODS reaction conditions. The results also indicated very good reusability of the synthesized catalyst after recycling five times.
