摘要: 采用环氧氯丙烷和糠醛组成双溶剂,研究了糠醛精制和双溶剂精制两种方法在回收废润滑油中的效
果。实验结果表明,双溶剂精制的最佳工艺条件为:剂油体积比1.0,V (环氧氯丙烷)∶V (糠醛)1.5∶1;糠醛精制的
最佳工艺条件为:剂油体积比1.5。在最佳的工艺条件下回收的废内燃机油的总回收率达到73.95%,回收油的粘度
指数为118.4。采用双溶剂精制法回收的油品质量比糠醛精制法好。

Abstract: Di-solvent is composed with epichlorohydrin and furfural. Two methods of furfural and di-solvent were investigated in recycle the used lubricating oil for effects. The experimental results show that the optimal technology conditions of di-solvent refining are the volume ratio of oxidant to oil 1.0 and V(epichlorohydrin)∶V(furfural) 1.5∶1. The optimal technology condition of furfural refining is the volume ratio of oxidant to oil 1.5 .Under the optimal technology conditions, the used engine oil total yield reach 73.95%. The properties of the recovered oil are viscosity index at 118.4, after append to a process of clay-adsorption, the recovered oil could be circularly used by harmonicing of proper quantities additions.
