摘要: 合成了一系列烷基碳链长度不同的1烷基3甲基咪唑硫酸氢盐离子液体,以质量分数为35% 的H2O2为氧化剂,考察了萃取时间、剂油体积比、温度等不同条件对模拟油品的脱硫效果,确定了最佳脱硫实验条件;在最佳实验条件下,考察反应体系对FCC汽油、柴油的脱硫效果。结果表明,[C3mim]HSO4离子液体的脱硫效果最好。在V([C3mim]HSO4 ) / V(H2O2) / V(模型油)=1∶1∶30,60 ℃的条件下反应90 min,对模拟油品及实际油品均有较高的脱硫率,对模拟油品一次脱硫率为88.38%,对抚顺石化公司石油二厂的FCC柴油的一次脱硫率在80%以上,FCC汽油经一次脱硫后,硫的质量分数下降至10 μg/g以下,显示了很高的工业应用前景。

Abstract: A series of Nmethylimidazolium hydrosulfate type of ionic liquids (ILs) bearing different length of alkyl chains were synthesized. The ionic liquids were applied both as extracting reagent and catalyst for the model or true oil desulfurization using hydrogen peroxide (35%) as the oxidant. The desulfurization conditions were optimized by varying extraction time, the ratio of ILs/oil, temperature and so on. Under the optimal conditions, the ILs were also used for the desulfurization of FCC gasoline and diesel. The results show that, [C3mim]HSO4 has the highest desulfurization rate. The best desulfurization rate was obtained after 1.5 hours under the condition of V([C3mim]HSO4)/V(H2O2 )/V(oil)=1∶1∶30 at 60 ℃ for the model oil (88.38%) and diesel (80%). The sulfur content of FCC gasoline has decreased to 10 μg/g below, which shows a very promising perspective for industrial applications.
