摘　　要：以环丁砜为溶剂进行再生废润滑油的研究。考察了精制温度、精制时间及剂油体积比对废润滑油精制效果的影响。结果表明,环丁砜精制的最佳工艺条件为:剂油体积比为1.4,精制温度120℃,精制时间为30 min。在该工艺条件下,再生精制油收率达到85.89%,再生油的黏度指数达103.62。同时,在精制时间为30 min恒定时,研究了精制温度、剂油体积比对再生油黏度指数的影响,并采用SPSS软件进行线性回归,得出了再生油黏度指数与精制温度、剂油体积比的回归方程。Sulfolance was used as solvent to regenerate waste lubricating oil. The influence of refining tem- perature, refining time and solvent to oil volume ratio of waste oil refining effect was investigated. The re- sult showed that the optimal condition of sulfolance refining： the solvent to oil volume ratio of 1.4,the re- fine temperature of 120 ℃ ,the refine time of 30 min. Under this proccss condition,the yield of the recov- ered oil was 85.89 %, the viscosity index was 103.62. Meanwhile,in the time of 30 min constant refining, studied refining temperature, solvent to oil volume ratio on recycled oil viscosity index and linear regres- sion using SPSS software, derived regenerative refined oil viscosity index and refining temperature, solvent to oil volume ratio the regression equation.
