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.

Summary: Extractive desulfurization using ionic liquids has attracted attention due to its simplicity and easy operating conditions. However, the selection of suitable cations and anions remains a challenge. This study developed a methodology to screen cation and anion molecules for maximum sulfur removal efficiency. Through genetic algorithm and principal component analysis, it was determined that certain imidazolium and pyridinium cations combined with specific anions are promising for extractive desulfurization. The selected ionic liquid, [HMPY][N(CN)2], was synthesized and evaluated, showing potential as a solvent for removing DBT or BT from n-heptane.

Summary: This study developed a new methodology for screening suitable cation and anion molecules to achieve maximum sulfur removal efficiency. The best structural descriptors were selected using Genetic Algorithm, and then the most proper cations and anions were chosen using Principal Component Analysis (PCA). It was concluded that ionic liquids with imidazolium and pyridinium cations with hexyl chain, combined with [N(CN)2] and [Ac] anions, are promising extraction solvents for 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 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: It is important to develop sustainable denitrogenation technology due to the impact of nitrogen compounds on the quality of fuel oils. To address the issues of incomplete denitrogenation and harsh conditions, an extractive denitrogenation method using eco-friendly piperazine-based ionic liquids (Pi-based ILs) was developed. The study evaluated the performance of the synthesized Pi-based ILs in removing pyrrole from oil and investigated the conformational relationship between denitrogenation performance and ILs structure. The results showed that the eco-friendly [C1Pi][Lac] exhibited the highest removal efficiency of 95.90% under optimal denitrogenation conditions.

Summary: The environmentally friendly N-1,N-1,N-3,N-3-tetramethyl -N-1,N-3-diphenylpropane-1,3-diaminium dichloride ionic liquid (ILc) was used as a catalyst for oxidative-extractive desulfurization of gas oil using H2O2 as an oxidizing agent. The structure of ILc was confirmed and its desulfurization efficiency was found to be 84.7% when using acetonitrile as a solvent. The ILc showed high reusability for at least six cycles without significant changes in performance or structure.

Summary: Bubble characteristics in pure IL [BMIM][BF4] and its binary mixtures with MEA and MeOH were compared for the first time, showing that binary mixtures had smaller mean bubble size, higher gas holdup, and interfacial area. MeOH had a more pronounced effect compared to MEA. Sparger pore size and temperature significantly influenced bubble properties in gas-pure IL.

Summary: A novel method for fabricating 3D porous carbon nanofiber/graphene oxide composite aerogels was developed for antibiotic removal from water, which showed significantly enhanced adsorption capacity due to the adjustable pore structure. The adsorbent effectively removed antibiotics over a wide pH range and exhibited lower inlet pressure in fixed-bed column adsorption compared to traditional particle adsorbents. The main possible mechanisms for the adsorption of antibiotics on the adsorbent included pi-pi electro-donor-acceptor interaction, pore filling, and hydrogen bonding.

Summary: The study investigated the inhibition effect of four antibiotics in dairy manure digesters, showing significant impacts on microbial communities with different dosing modes. FLO exhibited the most severe inhibition on biogas production and bacterial communities. A four-stage inhibition process on microbial community dynamics was proposed, and semi-continuous operation of antibiotics was found to be more efficient in inducing microbial community changes.
