摘　　要：在对活性剂、活化剂等对固体碱脱除硫化氢性能影响研究的基础上,对催化裂化汽油固体碱脱硫-固定床脱臭组合工艺进行了实验室小试,结果表明,固体碱完全可以取代液体碱而用于催化裂化汽油的精制。相对于液体碱洗-固定床脱臭工艺,无论再生前还是再生后,固体碱脱硫-固定床脱臭组合工艺使装置运转时间延长一倍以上。介绍了该组合工艺的流程设计和工业应用。Based on the study on the effects of activator and active agent on the solid caustic desulfufization, a laboratory test was performed for the combination process of solid caustic desulfurization-fixed bed sweetening for FCC naphtha refining. The results show that the solid caustic can replace liquid caustic in FCC naphtha refining. The production cycle of combination process of solid caustic desulfurization-fixed-bed sweetening is over two times that of liquid caustic washing and sweetening process no matter whether it is fresh or regenerated caustic. The process flow design and commercial application of the process are introduced.
