    Abstract: PURPOSE: A method for eliminating a nitrogen compound is provided to efficiently and economically remove an aromatic nitrogen compound using a simple extraction process using imidazole-based ionic liquid containing zinc. CONSTITUTION: A method for eliminating a nitrogen compound from hydrocarbons uses imidazole-based ionic liquid containing zinc which is generated by mixing ZnX_2 with imidazolium alkyl sulfate which is marked as a chemical formula 1. In the chemical formula 1, X is Cl, Br, or I and R1 and R2 are hydrogen or an alkyl group with C1-C10. The nitrogen compound is an aromatic nitrogen compound. A method for eliminating the nitrogen compound from hydrocarbons comprises a step of extracting the nitrogen compound from the hydrocarbons into the ionic liquid by contacting the imidazole-based ionic liquid containing zinc with the hydrocarbons and a step of separating the ionic liquid from the hydrocarbons.
