通过反应时间、反应温度、剂油质量比等条件对焦化蜡油中碱性氮化物脱除率及油品收率进行研究,结合正交试验确定了最佳反应条件.结果表明,反应温度59℃,剂油质量比0.021,搅拌速度300 r/min,反应时间15 min,沉降时间15 min时,油品收率为94.92%,碱性氮化物脱除率为85.42%.%In order to study the content of alkaline nitrogen compounds and the oil yield, using complexion to pretreatment of coking gas oil. There were many affecting factors on alkaline nitrogen compounds remove rate and the light oil yield, such as reaction time, reaction temperature, solvent to oil mass ratio and so on. The best experimental condition is defined by regular -crossed trial. The results show that the oil yield is 94.92％ and the separation rate of alkaline nitrogen compounds is 85.42％ at condition of reaction temperature 59 ℃, solvent to oil mass ratio 0. 021, stirring speed 300 r/min, reaction time 15 minutes and settling time 15 minutes.
