Abstract

Abstract:

Five kinds of functionalized ionic liquids ([CPL] [TBAB],[CPL]BF₄,[Bmim]HCO₃,[Bmim]OAc and[Bmim]Im) were synthetized, as well as heteropolyacid-ionic liquids ([CPL]₃PMo₁₂O₄₀ and[Bmim]₃PMo₁₂O₄₀) which have the same cations. Wet desulfurization by heteropolyacid is established. The desulfurization performance of the selected optimal desulfurizer is investigated at different absorption temperature and gas flow. The results show that [Bmim]₃ PMo₁₂O₄₀-[Bmim]HCO₃ has large capacity on desulfurization, and the optimal absorption conditions are over 40℃ and gas flow of 100 ml·min^-1.[Bmim]₃PMo₁₂O₄₀-[Bmim]HCO₃ can be simply regenerated by air.

Key words: ionic liquid, heteropolyacid, liquid-phase oxidation, H₂S, solvents, synthesis, absorption capacity

摘要：

合成了5种功能化离子液体（[CPL][TBAB]，[CPL]BF₄，[Bmim]HCO₃，[Bmim]OAc和[Bmim]Im）以及含有相同阳离子的多酸离子液体[CPL]₃PMo₁₂O₄₀和[Bmim]₃PMo₁₂O₄₀，构建了以功能化离子液体为溶剂的多酸液相氧化脱硫体系，优选出最佳脱硫剂，并考察了不同吸收温度、气体流量下最优脱硫剂的脱硫性能。结果表明[Bmim]₃PMo₁₂O₄₀-[Bmim]HCO₃脱硫效率最高，优化的吸收条件为温度高于40℃、气体流量为100 ml·min^-1；[Bmim]₃PMo₁₂O₄₀-[Bmim]HCO₃可以简单地用空气再生。
