“…The conversion rate of DBT increased to 94.5% with the increase in the O/S ratio to 5 but then decreased to 80% at an O/S ratio of 6. These findings suggest that increasing the O/S ratio can enhance the activity of SnO 2 -SBA-15 for the ODS reaction but only up to a certain point …”

“…These findings suggest that increasing the O/S ratio can enhance the activity of SnO 2 -SBA-15 for the ODS reaction but only up to a certain point. 143 Cellulose acetate (CA) is a polymer material that is costeffective and has controlled formability, making it a suitable carrier for catalysts in industrial applications. 144 results showed that increasing the quantity from 0.5 to 1.0 L/min led to a significant increase in the sulfur removal efficiency from 85.42 to 96.04%.…”

Nowadays, the scientific community is actively researching the advancement of a sustainable effective desulfurization technique. The development of alternative or supplementary approaches to desulfurization has rapidly progressed in recent years. Among these approaches, the oxidative desulfurization (ODS) process stands out as a highly promising method. This can be attributed to its notable selectivity, cost-effectiveness, mild reaction conditions, and overall efficiency. It is essential to consider the role of oxidants, catalysts, and operating conditions in optimizing the ODS process. This review examines a comprehensive understanding of the ODS process and its potential applications in desulfurization. It highlights the importance of oxidants, extractant solvent, and other operating conditions in the ODS process and discusses the different groups of catalysts that can be used. In addition, the review examines five distinct groups of heterogeneous catalysts used in the ODS process: transition metal oxides stabilized, polyoxometalates, ionic liquids, carbon materials, and porous materials. The role of ionic liquids in catalytic and extractive oxidation is also explored. In recent years, alternative or supplementary desulfurization methods have been rapidly developed. The review discusses the advantages and disadvantages of each approach. It explores various techniques that can be employed to mitigate the drawbacks associated with each system.

“…Various researchers have demonstrated the use of ILs in desulfurization of diesel as a promising and an environmentally benign technology . Several techniques have been investigated, including extractive desulfurization (EDS), oxidative desulfurization (ODS), combined extractive and oxidative desulfurization (ECODS), and desulfurization using immobilized ILs. − The main factors that influence the results obtained from each technique include the length of the alkyl chain of the IL cation, the type of cation and anion, temperature, pressure, and time. What all these techniques have in common is their superior ability to extract high-molecular-weight sulfur compounds, such as BT and DBT, at mild operating conditions relative to those of conventional HDS.…”

Defect engineering is often used to improve the performance of catalysts. Here, plasma etching was first used as a strategy to introduce defects to modify the phosphotungstic acid‐based ionic liquids (C14PWIL) catalyst for oxidative desulfurization (ODS) in fuel. The valence band/conduction band value of the catalyst indicates that the formation of oxygen vacancies plays an essential role in enhancing the oxidation capacity. In combination with X‐ray photoelectron spectroscopy results, the enriched electrons in the oxygen vacancies can increase the electron density on the catalyst surface, which promotes the electron migration process between the catalyst and H2O2, thus favoring the activation of H2O2 and enabling an efficient ODS process. The desulfurization efficiency of C14PWIL‐P at room temperature is 3 times that of C14PWIL, which exhibits good cycling stability.
