采用精密分馏手段，对山东齐鲁石化公司胜利炼油厂、济南炼油厂和九江石化总厂炼油厂催化裂化汽油脱臭前后的硫醇性硫分布进行了研究，并探讨了不同脱臭工艺对汽油不同沸程馏分的脱臭效果。结果表明，脱臭前ＲＦＣＣ汽油与ＦＣＣ汽油中硫醇性硫分布明显不同，而所有脱臭后汽油中，高级硫醇性硫所占含量较大、汽油中高级硫醇的含量多少是制约脱臭效率的关键因素。
By means of precision fractionation, the distribution of mercaptan sulfur before and after deodorization of catalytic cracking gasoline in Shengli Refinery, Jinan Refinery and Jiujiang Petrochemical Complex refinery in Shandong Qilu Petrochemical Company was studied, and the effects of different deodorization processes on the boiling range Deodorizing effect of the cut. The results showed that the distribution of mercaptan sulfur in RFCC gasoline and FCC gasoline before deodorization was significantly different, and the content of high-grade mercaptan sulfur in the gasoline after deodorization was relatively large. The content of high-grade mercaptan in gasoline was the limiting factor for the deodorization efficiency The key factor.
