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 Caustic soda pretreatment of caustic soda easy to produce large amounts of waste alkali solution, in order to completely eliminate the waste liquid pretreatment with alkali instead of caustic alkali pre-alkali washing method. However, the development of gasoline pretreatment of solid alkali is a challenging issue. The research status, development trend and application of solid alkali for gasoline pre-alkali washing are comprehensively discussed. The development direction of gasoline pre-alkali washing process is put forward: (1) to improve the waste liquid treatment level; (2) ; (3) pretreatment with solid base
