Abstract

ABSTRACT: Several imidazolium-based ionic liquids (ILs) with different anionic characteristics were investigated to determine their denitrogenation performances from the model oil containing indole or quinoline. Experiment results showed that [C4 mim]HSO4 exhibited an excellent denitrogenation performance, obtaining about 99% N-removal efficiency from the model oils. In addition, removal efficiency of quinoline and indole after five cycles of ionic liquid can reach 98.4% and 96.3%, respectively. The effects of the extraction temperature, time, and IL/oil mass ratio on the denitrogenation process are discussed in detail.
