摘要: 采用物理浸渍法将[C5mim]HSO4(1灢戊基灢3灢甲基咪唑硫酸氢盐离子液体)负载在分子筛表面,得到分子筛负载型离子液体。采用萃取氧化法,考察了负载型离子液体对催化裂化汽油的脱硫效果。结果表明,分子筛孔道大小对脱硫效果有一定的影响。以NaY分子筛为负载剂,质量分数为35% 的H2O2 为氧化剂,考察了氧化剂加入体积、萃取时间、剂油体积比等不同条件对催化裂化汽油的脱硫效果。确定了最佳脱硫实验条件为10g负载型咪唑硫酸氢根离子液体,100mLFCC汽油,1mLH2O2,40曟下反应60min后对汽油有较高的脱硫率,一次脱硫率可达94%,初始含硫质量分数为200毺g/g的汽油经一次脱硫后含硫质量分数可降至10毺g/g以下。反应结束后,通
过简单的倾倒使负载型离子液体与汽油分离,负载型离子液体通过回收后可重复使用。

Abstract: The immobilized 1amyl3methylimidazolium hydrosulfate ionic liquid was obtained by physical impregnation on molecular sieve. The oxidationextraction desulfurization effect of FCC gasoline using supported ionic liquid (SIL) were investigated. The results show that, the pore size of molecular sieve have certain impact on the desulfurization effect. With NaY molecular sieve as loading material, hydrogen peroxide (35%) as the oxidant,the desulfurization condition were optimized by varying oxidant dosage, extraction time, the ratio of ILs/oil, and so on. The best desulfurization rate was obtained after 60 min under the condition of 10 g SIL and 100 mL oil and 1 mL H2O2, at 40 ℃ with the sufur removal of 94% for FCC gasoline. The sulfur content of FCC gasoline has decreased to 10 μg/g below. After the reaction, the fuel oil and supported ionic liquid can be separated simply by decantation, the supported ionic liquid can be recycled .
