摘要： 为了提高润滑油的氧化安定性，用络合萃取的方法对某厂减三线脱蜡油进行了脱氮精制处理的小试实验。结果表明,[CM(15]糠醛与金属盐的混合溶剂能够有[CM)]效地脱除脱蜡油中的碱性氮化物，减三线脱腊油的碱氮量由432.32 μg/g降至91.99 μg/g，[KG*4]其脱氮率为78.12%。[KG*4]减三线脱蜡油糠醛精制工艺实验室的适宜操作条件为：加入助剂6 g/kg、精制温度118 ℃、精制时间20 min、剂油体积比2.0、沉降时间30 min。白土精制过程最佳操作条件为：白土加入质量分数为2.5%，精制温度150 ℃，精制时间20 min，白土不焙烧。

Abstract: In order to improve the oxidation stability of lube oil, the denitrogeneration refining laboratory scale test and pilotscale experiment had been done systematically for the second and third vacuum side dewaxed oil of No.1 refinery with the method of complex extraction. The results show that the mixed solvent of furfural and metallic salt can remove the basic nitrogen compounds in dewaxed oil effectively, the basic nitrogen compounds constituents in dewaxed oil were decreased from 432.32 μg/g to 91.99 μg/g,the denitrification percent was 78.12%. A fitting operation condition that the No.1 refinerys third vacuum side dewaxed oil was well extracted with furfural in laboratory was quantity of additive 6 g/kg,refining temperature 118 ℃,refining time 20 min, solvent to oil volume ratio 2.0,settling time 30 min.While a fitting operation condition that the refining oil was well extracted with atlapulgite quantity of atlapulgite 2.5%, refining temperature 150 ℃, refining time 20 min,atlapulgite wasnt torfiyed.
