摘要
咪唑类离子液体蒸汽压低、溶解性能好,被应用于油品中芳烃和硫化物的脱除。介绍了离子液体的特性及其合成方法,并对芳烃和硫化物脱除方法进行比较。综述了咪唑类离子液体脱除芳烃和硫化物不同方法的应用研究,对其优缺点进行比较,最后比较了离子液体回收方法,并展望了离子液体萃取脱硫前景。
Due to low vapor pressure,and good solubility of imidazole ionic liquids,they have been widely used in the removal of aromatics and sulfides of petroleum products.In this paper,the characteristics and synthesis methods of ionic liquids were introduced,and the removal methods of aromatic hydrocarbons and sulfides were compared.The studies on the removal of aromatics and sulfides by different methods with imidazole ionic liquids are reviewed,and the advantages and disadvantages of different methods were compared.Finally,the recovery methods of ionic liquid were compared and the prospects of desulfurization by ionic liquids were prospected.
