【摘要】 探讨了不同离子液体在不同条件下通过萃取降低汽油中硫含量的可能性.结果表明,较长碳链的DMImBF4离子液体具有很好的深度脱硫性能,并且能够重复使用.同时,研究结果还表明离子液体可以同时降低低碳烯烃的含量,而低碳烯烃的存在可以促进离子液体对汽油中硫的萃取.更多还原

【Abstract】 The technology of desulfurization of gasoline by extracting with ionic liquids was investigated. Some kinds of ionic liquids could decrease the content of sulfur as well as short chain alkenes in very mild conditions. Furthermore, the ionic liquids can be regenerated and reused easily. Therefore, extracting with ionic liquids is a possible approach for decreasing the content of sulfur and short chain alkenes of gasoline.更多还原
