“…The sustainability and the cost-effectiveness of the process can be assured by the use of recovered and recyclable catalysts and the application of environmental-friendly solvents, such as ionic liquids [19,20]. The former are able to behave as an extraction solvent and also as an immobilization medium for the homogeneous catalyst, containing catalyst and subtract in the same liquid phase [21,22]. Hydrogen peroxide is generally the preferred oxidant to use in these processes due to its high active oxygen content and the fact that water is the sole by-product [23,24].…”

An effective process to remove nitrogen-based compounds from fossil fuels without harming the process of sulfur removal is an actual gap in refineries. A success combination of desulfurization and denitrogenation processes capable of completely removing the most environmental contaminates in diesel under sustainable conditions was achieved in this work, applying polyoxometalates as catalysts, hydrogen peroxide as oxidant, and an immiscible ionic liquid as an extraction solvent. The developed process based in simultaneous oxidative desulfurization (ODS) and oxidative denitrogenation (ODN) involved initial extraction of sulfur and nitrogen compounds followed by catalytic oxidation. Keggin-type polyoxomolybdates revealed much higher reusing capacity than the related polyoxotungstate. Effectively, the first catalysts practically allowed complete sulfur and nitrogen removal only in 1 h of reaction and for ten consecutive cycles, maintaining the original catalyst and ionic liquid samples.

“…For achieving the deep or ultradeep desulfurization of fuel oil, acidic ILs/DESs as catalyst, solvent, and/or extractant as well as H 2 O 2 as an oxidant were used for oxidative-extractive desulfurization, and the ca . 98% desulfurization yield can be achieved whether ILs/DESs contain metal ions or not. − Except for H 2 O 2 , the solid peroxymonosulfate and the CH 3 COOH/H 2 O 2 mixture can also be selected as the effective oxidant to oxidize SCAs into sulfone. Although the oxidant type used is different, the oxidative-extractive desulfurization process is basically similar.…”

Heteroatom-containing aromatics (HACAs), such as oxygen-containing aromatics (OCAs), nitrogen-containing aromatics (NCAs), and sulfur-containing aromatics (SCAs), in high-temperature coal tar (HTCT) can be regarded as valuable chemicals. Ionic liquids (ILs)/deep eutectic solvents (DESs) play a crucial role for selectively extracting and purifying HACAs from HTCT, which can be attributed to the complex interactions, especially hydrogen bonds, between the ILs/DESs and HACAs. This paper mainly summarizes the separation of HACAs from a model oil and raw oil with ILs/DESs, the structural effect of ILs/ DESs on HACA separation, as well as the interactions between ILs/DESs and different solutes by experimental and computational chemistry. Subsequently, HACA separation with ILs/DESs from HTCT was summarized. This review was expected to screen and develop suitable ILs/ DESs with high selectivities to OCAs, NCAs, SCAs, and their homologues.

“…The existence of sulfur compounds in fuels as environmental pollutants is a major concern owing to their SO x emissions, which not only leads to acid rain pollution but also is harmful to human health. , As a well-applied industrial desulfurization technology, hydrodesulfurization is effective only for mercaptans, thioethers, disulfides, and so forth and is almost ineffective for thiophenic sulfur compounds (TSCs). , Therefore, the deep removal of TSCs from fuels is urgent. − So far, some conventional adsorbents, such as activated carbons and zeolites, − have been investigated for adsorption desulfurization, which is regarded as one of the most desired methods for deep desulfurization. − For instance, the zeolites were modified by metal ions (e.g., Cu, Ni, etc. ), alkali treatment, and carbon nanotubes’ enhanced porosity by hybridization with BN to improve performance. − However, the unregulated structure and inadequate specific surface area of the above adsorbents restrict the development for further enhancing the adsorption performance. − MOFs exhibit promising applications in deep desulfurization owing to their rich porous properties, open active sites, and adjustable backbones.…”

Adsorptive desulfurization over metal−organic frameworks (MOFs) remains a challenge in maintaining good performance in the presence of water. Herein, multimetallic Fe/ Ni/Cu/Zn-(MIL-88B)-on-(MOF-5) is first achieved through phase-competition-driven growth technology. The adsorption performance of thiophene (Th), benzothiophene (BT), and dibenzothiophene (DBT) in model fuels is systematically investigated at mild temperature and follows the order Fe/Ni/Cu/Zn-(MIL-88B)-on-(MOF-5) > MOF-5 > MIL-88B. Excellent adsorptive activity is mainly ascribed to the associative effects of multimetal active sites, suitable pore sizes and shapes, acid−base interactions, and complexation. Meanwhile, MIL-88B exhibits a "brick-wall" effect and effectively enhances the water stability of Fe/Ni/ Cu/Zn-(MIL-88B)-on-(MOF-5) more than does MOF-5. Fe/Ni/Cu/Zn-(MIL-88B)-on-(MOF-5) exhibits superior stability even after being immersed in water for 5 days, maintaining 77, 77, and 81% of the initial DBT, BT, and Th uptake capacities. After five periods of regeneration, more than 90% of the desulfurization capacity of Fe/Ni/Cu/Zn-(MIL-88B)-on-(MOF-5) was recovered. This work provides a new strategy for the synthesis of desirable MOF-on-MOF, promoting its potential application to adsorption desulfurization.
