A method of extracting nitrogen and sulfur compounds from petroleum distillates using ionic liquids is provided to remove the nitrogen compounds and sulfur compounds more effectively by using ionic liquid which is eco-friendly solvent. The method of extracting nitrogen and sulfur compounds from petroleum distillates using ionic liquids comprises the steps of mixing (i) the C5-C50 petroleum hydrocarbon distillates containing sulfur compounds, nitrogen compounds or mixture thereof and (ii) ionic liquids and then extracting and removing the sulfur and nitrogen compounds or the mixture thereof from the petroleum hydrocarbon distillate layer as ionic liquid layer through phase separation. The ratio of the ionic liquid and the petroleum hydrocarbon(solvent to oil;SOR) is 0.01-5. The extraction through phase separation is repeated more than two times. |
