“…Figure 4a shows that the sulfur removal was only 29.6% at 40°C and 58.6% at 50°C in 20 min, and it significantly improved to 81.7% as the temperature increased to 60°C. However, the final sulfur removal at 60°C was lower than that at 50°C probably due to the kinetic competition of the unproductive decomposition of H 2 O 2 (Yang et al 2017). 50°C might be the optimal reaction temperature, and the sulfur removal reached 97.2% at 120 min.…”

Deep eutectic solvents (DESs) are a new class of green solvents analogous to ionic liquids due to their biodegradable capacity and low cost. However, the direct extractive desulfurization of diesel oil by DESs cannot meet the government's standard. In this work, amphiphilic polyoxometalates were synthesized and characterized by FT-IR and mass spectrometry. The oxidative desulfurization results showed that benzothiophene (BT) could be completely removed by employing a [(C 6 H 13) 3 P(C 14 H 29)] 3 PMo 12 O 40 , DES (ChCl/2Ac) and H 2 O 2 system. It was also found that the organic cation of catalysts played a positive role in oxidative desulfurization. The reaction conditions, such as reaction temperature and time, the amount of catalyst and DES and H 2 O 2 /S (O/S) molar ratio, were optimized. Different sulfides were tested to determine the desulfurization selectivity of the optimal reaction system, and it was found that 97.2% of dibenzothiophene (DBT) could be removed followed by 80.7% of 4-MDBT and 76.0% of 4,6-DMDBT. After reaction, the IR spectra showed that the catalyst [(C 6 H 13) 3 P(C 14 H 29)] 3 PMo 12 O 40 was stable during the reaction process and the oxidative product was dibenzothiophene sulfone (DBTO 2). Furthermore, the catalyst can be regenerated and recycled for four runs with little loss of activity.

“…The oxidative system can be reused 20 times. Figure 15: Synthesis and structure of PILsPW [186] Yang coauthors [188] presented PIL/POM system for ODS ( Figure 16). The system poly[1vinyl, 3 alkylimidazolium]Mo8O26 (alkyl = C8, PVOMo; alkyl = C12, PVDMo; alkyl = C16, PVHMo) has mesoporous character and showed excellent results in sulfur removal.…”
