对煤衍生油中酚油馏分的物化性质进行了分析，并以乙二醇水溶液为萃取剂进行提酚工艺条件考察，结果表明，最佳流量为80~180 mL/min，最佳转速为2 000~2 400 r/min，最佳相比为0.4~0.7∶1。在理论计算的基础上，确定了2级逆流萃取和2级逆流反萃的工艺流程。在最佳工艺条件下，酚油粗酚提取率为92.61%，萃取剂回收率为93.46%，反萃剂回收率为92.10%。

The physicochemical properties of phenolic oil fractions in coal derived oil are analyzed and the process conditions for extracting phenolic compounds are investigated with ethylene glycol solution as extractant.The test results indicate that the optimum flow is in the range of 60-200 mL·min^-1,the optimum rotation rate is between 2 000 r·min^-1 and 2 400 r·min^-1 and the optimum phase ratio is in the range of 0.4:1 to 0.7:1.On the basis of theoretical calculation,it is confirmed to use the process routine with two stages countercurrent extraction and two stages countercurrent stripping.Under the optimum conditions and confirmed process flow,the extraction rate of crude phenol oil is 92.61%,the recovery rate of extractant is 93.46% and the recovery rate of stripping agent is 92.10%.
