It exhibited remarkable ability in effective desulfurization of model gasoline (thiophene in n-octane) and fluid catalytic cracking (FCC) gasoline, and the sulfur removal of thiophene in model oil (V(IL): V(oil)=0.08) could reach 93.9% in 50 min at 50 ℃. Low-sulfur (〈10 μg/g) FCC gasoline could be obtained after three extraction runs at an ionic liquid/oil volume ratio of 0.1, with the yield of FCC gasoline reaching 94.3%. The ionic liquid could be recycled 5 times with merely a slight decrease in activity.展开更多
