摘　　要：综述了国内外离子液体脱芳烃的研究进展,介绍了离子液体在萃取脱芳和催化加氢分离芳烃2个方面的应用。咪唑类和吡啶类离子液体用于萃取脱芳,在一定限度内增大阴阳离子的体积,有助于提高其对芳烃化合物的选择性。金属基离子液体对芳烃化合物催化加氢,可以达到精制油品和回收芳烃的双重目的。最后,指出离子液体在分离芳烃应用中的优势及今后的发展方向。The research development of ionic liquids in removing aromatics in recent years is reviewed.Imidazole and pyridine based ionic liquids used for extraction and dearomatization can help to improve the selectivity of aromatic compounds by increasing the volume of ions in a proper range.Metal-based ionic liquids in aromatics catalytic hydrogenation can refine oil and recycle aromatics.The advantages and future development of ionic liquids in removing aromatics are pointed out.
