“…To achieve ultra-low sulfur fuels, http severe processing conditions such as elevated temperature and high hydrogen pressure were required in the HDS process [7,8]. Then, as a complementary technology of HDS, oxidative desulfurization (ODS) has been extensively researched [9][10][11][12][13]. No hydrogen was consumed in the ODS system, where could achieve the purpose of deep desulfurization under mild reaction conditions [14].…”

“…The higher the ability to form a metastable emulsion, higher the oxidation activity and the better the separation after reaction either by demulsification or by decantation. Zhu et al [52,53] also report the preparation and application of various metal-based surfactant type ionic liquids peroxomolybdates and peroxotungstates for the oxidative desulfurization of fuel in oil/water mixture. The role of the quaternary ammonium cation was suggested to be the transfer of the catalytically active compounds to the sulfur containing aromatics thus enhancing the oxidation rate.…”

An overview of the recent advances in the field of polyoxometalate, ionic liquid hybrids, is proposed with a special attention paid to their application in catalysis, more precisely biphasic and heterogeneous catalysis. Both components of the hybrids are separately outlined pointing to their useful properties and potential for catalysis, followed by the description of the hybrids preparation and synergy between components in a large range of organic transformations. And finally a vision on the future developments is proposed.

“…The rate constants for the apparent conversion of DBT can reflect the oxidative reaction process, and were obtained from the pseudo-first equation (ln(C 0 /C) = kt, where C 0 and C are the sulfur contents at time zero and time t and k is the first-order rate constant) [21,30,31]. The rate constants for the apparent conversion of DBT at various temperatures are listed in Table 2 …”

Deep desulfurization of liquid fuels is an important and challenging issue in worldwide petroleum refining industry. Extraction and catalytic oxidative desulfurization (ECODS) of liquid fuels using a series of ionic liquids (ILs) with two functionalized groups, such as [(CH 2 ) 2 COOHmim]Cl/nFeCl 3 , [(CH 2 ) 2 COOHmim]Cl/nZnCl 2 , and [Amim]Cl/nFeCl 3 , was studied. In the ECODS, the ILs were used as both extractant and catalyst and 30 wt% hydrogen peroxide (H 2 O 2 ) solution as oxidant. The effects of molar ratios of [(CH 2 ) 2 COOHmim]Cl (or [Amim]Cl) to FeCl 3 (or ZnCl 2 ) in ILs, H 2 O 2 /sulfur (O/S) molar ratio, reaction temperature, and the nature of sulfur compounds on sulfur removal were investigated. The natures of the functional groups (-COOH, -CH 2 -CH=CH 2 ) in cations and the acid strength of anions play important roles in the ECODS and affect the reaction time, temperature, and desulfurization efficiency of different substrates. Also, nitrogen-containing compounds (pyridine, pyrrole, and quinoline) could be removed simultaneously in the ECODS and had different effects on dibenzothiophene removal. ionic liquids, desulfurization, denitrogen, fuel
