摘要
A series of novel aqueous ionic liquids(NMP-FeCl_(3)-nH_(2)O)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-FeCl_(3) could effectively improve the desulfurization rate and selectivity,and the optimal amount of water was equal to 5%-10% of NMP.Finally,the possible desulfurization mechanism activated by a small amount of water was proposed.
