Batch Oxidative Desulfurization of Model Light Gasoil over a Bimetallic Nanocatalyst

Abstract

A novel AgO/ZnO/HY‐zeolite bimetallic nanocatalyst was designed and synthesized by an impregnation method. The purpose of this nanocatalyst was to remove dibenzothiophene as the primary sulfur content from a model light gasoil in a catalytic oxidative desulfurization (ODS) process. The characteristics of the synthesized nanocatalyst were determined by Fourier transform IR spectroscopy, Brunauer‐Emmett‐Teller analysis, scanning electron microscopy, and X‐ray diffraction. The ODS study revealed high sulfur conversion under optimal ODS reaction conditions and very good reusability of the catalyst after recycling five times.

“…The organic sulphur compounds present are mainly converted into SO3, which readily dissolves in water vapour to form sulphuric acid. The generated sulphuric acid is then changed into fine particles that can enter human lungs and cause lung cancer [1][2][3][4]. Furthermore, the presence of sulphur compounds in petroleum products causes corrosion problems in petroleum refinery equipment and poisons downstream catalysts [5][6][7][8].…”
