摘要/Abstract

摘要： 分别考察了4种萃取剂在单一或复配条件下，对3种模拟汽油中单一含硫化合物及FCC汽油70～160 ℃切割馏分的萃取脱硫效果，效果皆佳的萃取剂为环丁砜。考察了操作温度、剂油比、环丁砜和四甘醇复配对脱硫率的影响。结果表明：温度对萃取脱硫率的影响较小。适宜的萃取条件为温度35 ℃，剂油比3∶1。环丁砜单一溶剂萃取脱硫效果较优。

Abstract: The extraction performance of four solvents for deep desulfurization the 70—160℃ fraction of FCC gasoline and modeling gasoline containing three sulfur compounds was investigated respectively. The extraction desulfurization performance of sulfolane was best among the solvents examined. The influences of the ratio of solvent to oil, extraction temperature and composition of the mixing solvent on extraction performance were studied. The effect of extraction temperature on the percentage of sulfur removal from FCC and modeling gasoline was not significant. The suitable extraction conditions were determined as follow: ratio of solvent to oil 3∶1 and temperature 35 ℃. The results indicated that extraction performance of sulfolane is better than that of the mixing solvent.
