摘　　要：催化裂化轻汽油醚化工艺是降低汽油烯烃而基本不损失汽油辛烷值的理想工艺,但是轻汽油中的微量含氮化合物会导致醚化工艺的催化剂中毒,必须将其脱除。本文对脱除催化裂化轻汽油中氮化物的主要方法,包括萃取法、吸附法、预加氢和其它方法进行综述,总结各种方法的优缺点,阐述氮化物脱除技术的新进展,并对未来催化裂化轻汽油脱氮的发展方向做出展望。The etherification of FCC light gasoline is an ideal process to reduce olefin content in gas- oline and with minimum octane loss, but trace amount of nitrogen compounds in the gasoline may lead deactivation of etherification catalyst, so these nitrogen compounds should be removed. In this paper, methods for removing nitrogen compounds in FCC light gasoline, such as extraction, adsorption, pre-hydrogenation and etc. are summarized including the benefits and limitations of each process and new pro- gresses in denitrogenation technology. The future developing trend of removing nitrogen compounds in FCC light gasoline is also discussed.
