Abstract: A low viscosity ionic liquid [Amim]Cl/ZnCl2 is synthesized, and used as extractant to remove basic nitrogen compounds from shale oil diesel oil. The nitrogen removal efficiencies of this ionic liquid are investigated under different temperature, mass ratio of extractant to oil and extraction time. The results show that the removal rate of basic nitrogen compounds by [Amim]Cl/ZnCl2 can reach 86% when the reaction temperature is 30℃, the mass ratio of extractant to oil is 1:7, reaction time sustains 20 minutes and settlement time takes 2 hours. After four times of repeated tests, the removal rate can still reach 53%.
