摘要
分析了离子液体的脱氮原理,并按阴离子类型对其进行了分类,着重介绍了各类离子液体在油品非加氢脱氮中的应用。相对于其他非加氢脱氮技术,离子液体脱氮技术具有选择性高、化学及热稳定性高、操作工艺简单、易回收、污染少、脱氮率高等优点。进一步提高离子液体的重复使用性、稳定性、选择性和降低其生产成本是该领域今后研究工作的主要目标。
The principle of denitrogenation with ionic liquids is analyzed. According to anion type, ionic liquids are classified and the applications of various types of ionic liquids in non-hydrodenative denitrification of oil products aremainly introduced. Compared with other non-hydrodenitrogenation technology, denitrogenation technology with ionic liquids possess many advantages, such as： high selectivity, high chemical and thermal stability, simple operating process, easy recovery, less pollution, high denitrification rate, and so on. The primary objectives for further research are pointed out, such as improving the reusability, stability, selectivity of ionic liquids and reducing the production cost.
