Synthesis of hydrogel composites -based deep eutectic solvents fordesulfurization from Fuel

Fuel combustion releases sulfur-containing compounds, which react to form environmentallyharmful sulfur oxides that pose a threat to human health. To mitigate these negative effects, it isessential to pre-treat the fuel oil through the desulfurization process. One promising approach is usingthree-component metal deep eutectic solvents (MDESs) and the hydrogels obtained from thesesolvents. Composite materials (synthesized from DES) effectively reduce sulfur content in fuel oil.The effects of various factors on the removal rate of dibenzothiophene (DBT) in n-octane simulatedoil were investigated which showed a very high efficiency and was used up to six times cyclically.The characterization results of DESs through FT-IR and ۱H NMR showed that DESs were formedby hydrogen bonding interaction. Extractive desulfurization combined with oxidation wasestablished, where DESs were used as extractants and catalysts.
