摘要： A series of novel aqueous ionic liquids (NMP-FeCl3-nH2O) were prepared and the effects of water in the aqueous ionic liquids on desulfurization rate and selectivity of simulated FCC gasoline were investigated. The results showed that adding a small amount of water into the ionic liquid NMP-FeCl3 could effectively improve the desulfurization rate and selectivity, and the optimal added amount of water was 5wt% ~ 10wt% of NMP. Finally, the possible desulfurization mechanism activated by a small amount of water was proposed.
