Abstract
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.
