摘要:

以固体碱洗代替传统的ＮａＯＨ液体碱洗是解决当前ＦＣＣ汽油预碱洗明废碱液排放的最有效途径之一。开发物ＳＢ－１固体碱具有吸收酸性物质（Ｈ２Ｓ）能力强、机械强度高、再生简单等特点。本文介绍了ＳＢ－１固体碱的制备方法及其性能，并在实验室模拟工业装置上考察其预碱洗效果，结果表明：经ＳＢ－１碱洗汽油脱臭催化剂寿命比未碱洗持大大增长，与液体碱洗效果相同，说明ＳＢ－１固体碱能够代替液体碱预碱洗。

Abstract:

Replacing caustic solution by solid base in the precaustic wash of FCC gasoline is one of the best effective way for solving waste caustic bleeding. The paper introduces the preparation and property of solid base SB-1, the solid base possesses strong abso
