Summary: This review article presents the use of deep eutectic solvents (DES) in removing sulfur pollutants from transportation fuels, highlighting the urgent need to reduce the impact of fossil fuels impurities on outdoor air pollution. A comparative evaluation with Ionic Liquids (ILs) shows that DES has advantages in extracting sulfur contaminants, but the efficiency gap between simulated matrices and real fuels is still a challenge to be addressed.

Summary: The study prepared magnetic functional MOF-199 composites with good adsorption performance and easy recovery by solvothermal method for removal of thiophene from model oil. Experimental results showed that the adsorbent achieved the best desulfurization effect at 30 degrees Celsius and an oil to adsorbent ratio of 100. After 5 reuses, the adsorbent still exhibited excellent desulfurization performance.

Summary: Metal-based coordinated ionic liquids have attracted attention for their high sulfide selectivity and desulfurization rate in extractive desulfurization. In this study, the interactions between NMP-FeCl3 and TH in the presence of model oil were systematically investigated using density functional theory. Various types of interactions, including S-Fe coordination, were observed. S-Fe coordination was identified as the predominant desulfurization mechanism for extracting TH from fuel oils.

Summary: The increasing energy consumption has led to a rise in sulfur emissions, causing economic and health issues, as well as impacting the efficiency of diesel engine emission control systems. To combat this, research is being conducted on various desulfurization technologies, including conventional methods like hydrodesulfurization and alternative processes such as adsorptive, extractive, oxidative, and bio-desulfurization. Factors such as DES selection, extraction temperature, extraction time, DES regeneration, and multistage extractions play a crucial role in the desulfurization efficiency, with deep eutectic solvents showing promise as a less toxic and more efficient alternative for extractive desulfurization.

Summary: Silica-based porous ionic liquids (OS-PIL) functionalized with quaternary ammonium salt were successfully synthesized to remove dibenzo-thiophene (DBT) in model fuel. The OS-PIL exhibited high extraction activity with a Nernst partition coefficient of 4.22. The synergistic effect between porous materials and ionic liquids, along with the multiple sites in the quaternary ammonium salt, greatly contributed to the high extractive desulfurization efficiency.

Summary: This review focuses on the physicochemical properties of deep eutectic solvents (DESs) and their applications in desulfurization processes, with particular emphasis on recent advances in selective aerobic oxidation desulfurization (AODS) and the biomimetic approach coupling DESs with polyoxometallates (POMs). The strategy of combining DESs as multifunctional agents with POMs as electron transfer mediators offers a novel path for oxidation catalysis, overcoming challenges such as O-2 activation. The potential applications and future opportunities of DESs in catalysis science are also discussed.

Summary: This study introduces a novel three-body deep eutectic solvent (DES) synthesized from nitromethylpyrrolidone (NMP) as a hydrogen bond acceptor (HBA) and benzoic acid (BEN) and water (H2O) as hydrogen bond donors (HBDs). It is used for extractive desulfurization (EDS) of model oil and analogue FCC gasoline. The results show that the three-body DES has higher activity, lower viscosity, and lower volatility, and the best desulfurization performance is achieved by a DES with a mass ratio of 8NMP/2BEN/0.06H2O containing 6 wt % water.

Summary: By introducing porous boron nitride into ionic liquids, the efficiency of sulfur extraction from fuel oil can be improved. Using m-BN-PIL as an extractant under optimized conditions achieves desulfurization performances of 59.2% and 61.8% for dibenzothiophene and 4-methyldibenzothiophene, respectively. After four stepwise extractions, the extraction efficiency over dibenzothiophene reaches 98.2%, achieving deep desulfurization of fuel oil.

A Keggin-type PW11Zn was encapsulated within MOF-808 using an environmentally friendly solvothermal approach. The catalyst showed excellent catalytic activity for oxidative desulfurization of dibenzothiophene (DBT) in liquid fuel oil, with a 99.4% DBT conversion and a removal capacity of 86.85%. The catalyst displayed good reusability and no significant loss in activity after eight cycles of recycling. Kinetics and thermodynamic analysis of the oxidation reaction were also conducted.
