摘要/Abstract

摘要： 在新型复合溶剂回收废润滑油的工艺研究中,采用正交试验法,在4种不同水平下考察了操作温度、
精制时间、剂油体积比、次溶剂二甲基甲酰胺(DMF)加入量、助溶剂(聚醚2070)加入量等5个因素对精制效果的影
响。极差分析结果表明,DMF和聚醚2070的加入量是影响收率的关键因素;聚醚2070的加入量对黏度指数影响较
小,而剂油体积比和DMF加入量对黏度指数的影响大。均值分析结果表明,该溶剂的最佳精制条件为温度80 曟,
精制时间30min,剂油体积比1.5暶1,DMF加入量15%,聚醚2070加入量0.2%。在最佳实验条件下,再生油收率
可达91.7%,其黏度指数可达108.8。

Abstract: In the new mixed solvent of waste lubricant regeneration research process, applied the orthogonal method, investigated the refined effect of the operating temperature, refining time, the ratio of oil to solvent, the amount of the second solvent added to (DMF), the amount of the auxiliary solvent (polyether2070) added to five factors in four different levels. The range analysis shows that the added amount of the DMF and polyether2070 are the key factors of influencing the yield, as the change of the amount of polyether 2070 added to has little effect on the viscosity index, while the volumic ratio of solvent to oil and the amount of DMF added to on the viscosity index of the big influence.Mean analysis shows that the best refining conditions of the solvent is for the temperature being 80 ℃, the refine time being 30 min, the volumic ratio of solvent to oil being 1.5∶1, the amount of DMF added to being 15%, polyether2070 added to being 0.2%. In the optimal experimental conditions, the total yield of renewable lubricant reaches 91.7%, its viscosity index reaches 108.8.
