Sažetak
Ionic liquid (IL) N-methyl pyrrolidone dihydrogen phosphate ([Hnmp]H2PO4) was synthesized and its structure was characterized with FT-IR spectroscopy and 1H NMR. The denitrogenation performance of the ionic liquid was investigated using Fushun shale
diesel oil that included 0.52 w% basic nitrogen as feedstock. Experiment results showed that under the operating conditions with temperature of 30 °C, 1:7 (w/w) IL: oil, reaction time of 20 min, and settling time of 2 h, the ionic liquid exhibited good denitrogenation
performance achieving 86.27 % basic N-extraction efficiency and the yield of refined diesel oil can reach more than 90 %. In addition, the basic N-removal efficiency can still reach 54 % during four recycles of the ionic liquid.
