| 摘要: | 合成3种吡唑类离子液体[BuMe3Py]PF6、[BuMe3Py]BF4和[BuMe3Py]NO3, 研究了它们对模拟油品中吡啶的脱除性能. 选取效果较好的[BuMe3Py]BF4, 考察离子液体和模拟油品的质量比(剂油比)、反应时间、温度以及沉降时间对脱氮效率的影响. 结果表明, 剂油比和反应温度对脱氮效率影响较明显, 较大的剂油比、较低的反应温度有利于脱氮效率的提高. 在剂油比1:3、反应温度25℃、反应时间2h、沉降时间40min的条件下, 脱氮效率可达94.6%. 重复利用实验结果表明, 重复利用5次仍具有较好的脱氮效率. |
| Abstract: | Three pyrazolium ionic liquids, [BuMe3Py]PF6, [BuMe3Py]BF4, and [BuMe3Py]NO3, are synthesized and the removal efficiency of pyridine from simulated oil is tested. Based on the preferable [BuMe3Py]BF4, the effect of mass ratio (IL/oil), reaction time, temperature and settlement time are investigated. The findings show that the larger mass ratio of IL/oil and lower temperature will improve the denitrification efficiency significantly. 94.6% efficiency is achieved given an optimum condition at 25℃ with 1:3 of mass ratio (IL/oil), 2 h of reaction time, and 40 min of settlement time. The results of regeneration experiment reveal that [BuMe3Py]BF4 remains high denitrification efficiency after five times reuse. |
