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.
