汽油预碱洗工艺的发展及固体碱的应用

用苛性碱液对汽油进行预碱洗时易产生大量废碱液，为彻底消除废液提出了用固体碱预处理代替苛性碱液预碱洗的方法。但是，开发汽油预处理固体碱是具有挑战性的课题。对汽油预碱洗的研究现状、发展趋势和固体碱的应用进行了综合论述，提出了汽油预碱洗工艺的发展方向：（１）提高废液处理水平；（２）采用氨水预碱洗方法；（３）用固体碱进行预处理

ADVANCES IN PREWASHING OF GASOLINE AND APPLICATIONS OF SOLID BASE

As caustic solution prewashing of FCC gasoline discharges lots of lye, it is necessary to improve the process. The solid base pretreating of FCC gasoline will completely avoid this problem. Simultaneously, the application of solid base to gasoline refining process is discribed. It is necessary and difficult to develop solid alkali. The development of alkli pretreating for gasoline depends on improvement of waste solution treating process, applications of ammonia pretreating and solid alkali pretreating.
