“…As a nonhydrodesulfurization method, oxidative desulfurization (ODS) is one of the most beneficial techniques that can be conducted without any hydrogen usage under normal conditions at low temperatures (∼50 °C) and atmospheric pressure. Different oxidants, such as hydrogen peroxide (H 2 O 2 ), , O 2 , , ozone (O 3 ), ,, tert -butyl hydroperoxide, peroxy acids, and NO 2 have been used in the ODS process to diminish sulfur compounds in fuels. , The ODS process contains two main steps. First, the sulfur compound is oxidized to its sulfone or sulfoxide derivatives in the presence of oxidizing agent.…”

Over the past decades, the desulfurization of fuel oils has been known as one of the most challenging processes in petroleum refineries due to economic considerations. The presence of sulfur compounds results in SO x emissions, detrimentally affecting the equipment of refineries, the environment, and human health. In this direction, the unique features of ionic liquids have introduced them as a beneficial alternative for conventional desulfurization of fuel oils using traditional organic solvents. In this review, we aim to study ionic liquids used in different desulfurization processes of fuel oils, including hydrodesulfurization (HDS), oxidative desulfurization (ODS), extractive desulfurization (EDS), extraction combined with oxidation desulfurization (EODS), extractive and catalytic oxidative desulfurization (ECODS), and liquid–liquid extraction (LLE). Furthermore, governing factors, including temperature, mixing time, reusability of ionic liquids, stirring speed, sulfur structure nature, and molar and mass ratios of oxidants, ionic liquids, and catalysts, have been reviewed in detail.

“…The following substances were tested as oxidants for ODS in liquid media: sulfuric acid, nitric acid, potassium permanganate, sodium bromate, potassium persulfate, hypochlorites, carboxylic and sulfonic peracids, tert-butyl hydroperoxide (t-BuOOH), tertamyl hydroperoxide, etc., as well as hydrogen peroxide (H 2 O 2 ), pure or in combination with short-chain organic acids, etc. [17,25,[38][39][40][41]. Many of these substances were found to be inefficient, mainly due to the limitations connected with low selectivity, low end product output, high cost, toxicity, etc.…”

In this paper, the current advantages and disadvantages of using metal-containing nanocatalysts (NCs) for deep chemical oxidative desulfurization (ODS) of liquid fuels are reviewed. A similar analysis is performed for the oxidative biodesulfurization of oil along the 4S-pathway, catalyzed by various aerobic bacterial cells of microorganisms. The preferences of using NCs for the oxidation of organic sulfur-containing compounds in various oil fractions seem obvious. The text discusses the development of new chemical and biocatalytic approaches to ODS, including the use of both heterogeneous NCs and anaerobic microbial biocatalysts that catalyze the reduction of chemically oxidized sulfur-containing compounds in the framework of methanogenesis. The addition of anaerobic biocatalytic stages to the ODS of liquid fuel based on NCs leads to the emergence of hybrid technologies that improve both the environmental characteristics and the economic efficiency of the overall process. The bioconversion of sulfur-containing extracts from fuels with accompanying hydrocarbon residues into biogas containing valuable components for the implementation of C-1 green chemistry processes, such as CH4, CO2, or H2, looks attractive for the implementation of such a hybrid process.

“…Desulfurizations that have been explored recently include oxidation, extraction, biological techniques, and adsorption [13]. The literature on desulfurization processes shows that the nontraditional method of removing sulfur from oil fractions is oxidative desulfurization [14][15][16][17][18][19][20][21].…”

In the present study, the combined oxidation-emulsification was used to desulfurize diesel fuel with a hydrogen peroxide-acetic acid oxidation system. A full 20 central composite design response surface method was employed to study the effect of 5-20% oxidant range, 40-100ᵒC temperature range and 20-90 min time. A 0.781% sulfur content was obtained at 12.5 wt% oxidant ratio, 65ᵒC temperature 60 min via the oxidation process. The effect of emulsification desulfurization on oxidized diesel fuel was investigated using five surfactants: cetyltrimethylammonium chloride (cationic), nonylphenol ethoxylates (nonionic), alkylbenzene sulfonate (anionic), tween 80 (nonionic), and 1-hyroxy-2-(trimethylammonio) ethane-1-sulfonate (Amphoteric). A 0.598% sulfur content was obtained using alkylbenzene sulfonate. The desulfurize diesel fuel was charactizied using GC-MASS, IREX, and FTIR. The results indicated that the combined oxidation-emulsification process may be used to desulfurize diesel.
