“…In addition, heterocyclic sulfides and their derivatives cannot be removed completely due to resistance at high temperatures. Therefore, alternative desulfurization techniques have been used, such as extraction, bio-desulfurization, adsorption, photooxidation, and oxidation [4,5]. Among these technologies, oxidative desulfurization (ODS) offers advantages such as simplicity, lower costeffectiveness, and carrying out at middle operating conditions [6].…”

In this study, the incipient wetness impregnation (IWI) method was used to prepare tin oxide nanoparticles supported on reduced graphene oxide nanosheets (SnO2/rGO). Characterize of catalyst composite were analyzed by X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FTIR), Field emission scanning electron microscope (FESEM), energy dispersive X-ray spectroscopy (EDX), and Raman spectroscopy. The activity of the SnO2/rGO catalyst was evaluated in the catalytic oxidation process of dibenzothiophene (DBT) for modeled oil and diesel fuel in the presence of H2O2 as an oxidant. Optimum reaction conditions (the loading quantity of the tin oxide, the concentration of dibenzothiophene, the time of reaction, the temperature, the amount of oxidant, and the catalyst dosage) were investigated in a batch reactor. High-value of dibenzothiophene (DBT) removal from modeled oil samples was 79% at temperature = 60 ◦C, reaction time = 90 min, catalyst dosage = 0.04 g, amount of H2O2 = 0.375 mL, and 385 ppm concentration of dibenzothiophene. Catalyst activity at the same operating condition was also investigated for diesel fuel and the removal of sulfur was 41%

“…Shi et al [31] found that the lower electron density upon sulfur atom led to lower activity in removing of sulfur related to the electron density of thiophene, BT, DBT and the oxidation reactivity of the model sulfur compounds has been conducted based on the oxygen as an oxidant and complex solid as a catalyst. Abdulateef et al [22] have used the ODS of sulfur compounds found in kerosene using several different reactor temperatures, different reaction time and different catalyst weight in a batch reactor based on a prepared nano catalyst of manganese oxide (ZnO-MgO/ɣ-Al2O3), and high sulfur removal was observed. Nawaf et al [21] have examined the ODS process of kerosene based on composite nano catalyst (18%ZnO/ɣ-Al2O3) prepared by thermal coprecipitation method in a batch system.…”

Oxidative desulfurization process (ODS), enhanced with a novel metal oxide (Ag ions) as an active component over nano-zeolite that has not been reported in the literature, is used here to improve the fuel quality by removing mercaptan (as a model sulfur compound in the light naphtha). Nano-crystalline (nano-support (Nano-zeolite)) composite is prepared by Incipient Wetness Impregnation method loaded with a metal salt to obtain 0.5, 1 and 1.5% of Ag2O3 over Nano-zeolite. The new homemade nano-catalysts (Ag2O3/Nano-zeolite) prepared are characterized by Brunauer–Emmett–Teller (BET) (surface area, pore volume and pore size), X-ray Diffraction (XRD), Fourier Transform Infra Red (FTIR), and Scanning Electron Microscopy (SEM) analysis. The ODS process is then used to evaluate the performance of the catalysts for the removal of sulfur at different reaction temperatures (80–140 °C) and reaction times (30–50 min) in a batch reactor using the air as oxidant. 87.4% of sulfur removal has been achieved using 1% silver oxide loaded on Nano zeolite (1% of Ag2O3/Nano-zeolite) giving a clear indication that our newly designed catalyst is highly efficient catalyst in the removal of sulfur compound (mercaptan) from naphtha. A new mechanism of chemical reaction for sulfur removal by oxygen using the new homemade catalyst (Ag2O3/Nano-zeolite) prepared has been suggested in this study. The best kinetic model parameters of the relevant reactions are also estimated in this study using pseudo first order technique based on the experimental results.
