Zusammenfassung: | One-pot extractive and biomimetic catalytic oxidative desulfurization of model oil in ionic liquid.
[Display omitted]
•An eco-friendly and efficient process for desulfurization of fuel oil was reported.•The system showed good stability and performance for desulfurization of fuel oil.•The system could be reused for 6 times without significant decrease in activity.•The reaction system was further applied for the desulfurization of a real diesel fuel.
An eco-friendly and efficient process for extractive and biomimetic catalytic oxidative desulfurization in fuel oil under mild conditions with H2O2 as oxidant, ionic liquids as extractant and Fe(III) porphyrins as catalysts was reported. The catalytic reactivity of different Fe(III) porphyrins had been investigated in ionic liquids, and the catalysts showed good stability and performance in [Bmim]PF6. The possible mechanism seemed that sulfur-containing compound was oxidized to corresponding sulfone with [(Porp)FeIII-OOH] or/and [(Porp)FeIII(O)+·], which generated in ionic liquids phase. The different reaction conditions such as temperature, mole ratio of H2O2 and sulfur compounds were investigated in the catalytic system with Fe(III)(p-CH3TPP)Cl (catal. III) and [Bmim]PF6. The system could be recycled 6 times without obvious decrease of desulfurization efficiency. The reaction system was also applied for the desulfurization of a real diesel fuel. |
