摘要

摘要: 合成了一系列功能化酸性离子液体并用于模拟油品中非碱性氮-吲哚的脱除。结果表明，离子液体的阴离子对脱氮率有较大影响，离子液体的酸性越强，对吲哚的选择性脱除效果越好，不同阴离子的脱氮率顺序为：HSO₄^- > CF₃COO^- > H₂PO₄^- > CH₃COO^-。以（CH₃CH₂）₃N（CH₂）₃SO₃HHSO₄为例，考察了剂油比、剂水比、沉降时间、反应时间和温度对油品脱氮率的影响。结果表明，在优化的工艺路线下，（CH₃CH₂）₃N（CH₂）₃SO₃HHSO₄对油品中的吲哚脱除率可达99.12%，重复使用六次后，脱氮活性未见明显降低，具有良好的稳定性，。

Abstract: A series of functionalized acidic ionic liquids (ILs) were synthesized and used to remove non-basic nitrogen (indole) in model oil. The results indicate that the anions have a significant impact on the denitrification efficiency; the denitrification rate of the ionic liquids with various anions increases with their acidity, i.e. it follows the order of HSO₄^- > CF₃COO^- > H₂PO₄^- > CH₃COO^-. The effects of IL/oil ratio, IL/H₂O ratio, settlement time, reaction temperature and time on the denitrification efficiency of (CH₃CH₂)₃ N (CH₂)₃SO₃H HSO₄ were well considered. The results showed that 99.12% indole nitrogen in the oil can be removed with (CH₃CH₂)₃N(CH₂)₃SO₃HHSO₄ under the optimum condition; furthermore, the IL exhibits high stability and its denitrification activity remains almost unchanged even after being reused for six times.
