摘　　要：根据溶剂精制再生废润滑油环保、经济、高效的特点，采用单因素实验方法，应用极性溶剂为萃取剂、乙二胺为絮凝剂，组合精制再生废润滑油。最佳工艺条件为：萃取剂为正丁醇，精制时间为15min，精制温度为25℃，剂／油质量比为5：1，絮凝剂添加比例为1．0％。以该精制工艺操作，再生油性能指标得到明显改善，黏温指数达130以上，闪点达200℃，酸值为0．05mg·g-1，灰分质量分数降低到0．01％以下，金属元素含量显著下降，再生油产率为80．6％，各项性能基本上符合HVI150基础油指标，表明该精制工艺再生废润滑油可行，应用前景广阔。Solvent refining is known for its low pollution, low cost and high efficiency in waste lubricating oil recycling. With the extraction solvents of polar solvents and the floeculant of 1,2 - ethanediamine, the single-factor experimental method is used to regenerate waste lubricating oil. The optimal process conditions are obtained as follows：the polar solvent being n-butanol, the refine time being 15 min,the refine temperature being 25 ℃ ,the mass ratio of solvent to oil being 5：1 ,and the 1,2 - ethanediamine amount being 1.0%. The properties of regenerated oil are improved greatly,with viscosity index exceeding 130, the flash point reaching 200 ℃ , the acid number being 0.05 mgmg·g-1, and the ash content decreasing below 0.01%. Metallic content decreases dramatically. Under the optimal technology conditions ,the total yield of regenerated oil reaches 80.6%. The quality of the regenerated oil could reach the HVI150 standard of base oil, showing this technology of regeneration is a promising way to regenerate waste lubricating oil.
