| 摘 要： | 将异丙醇与糠醛配成双溶剂,分别采用糠醛单溶剂及异丙醇与糠醛的双溶剂对工业废润滑油进行溶剂精制,对回收工艺进行了研究。结果表明:双溶剂精制的效果优于糠醛单溶剂精制的效果。其最佳工艺条件是:精制温度为75℃,异丙醇与糠醛的体积比为1∶1,剂油体积比为1.5∶1。在最佳工艺条件下,所回收油品的粘度指数为119.5,折光率为1.476 6,色度为1.0,凝点为-15.8℃,闪点为218.4℃,硫质量分数为0.026%,油品的总收率为72.5%。

| Abstract: | Two methods including furfural refining and dual-solvent(2-Propanol and furfural) refining were investigated respectively in recycling the used industrial lubricating oil.The results show that the performance of dual-solvent refining is better than furfural refining.The optimum process condition is as follows: refining temperature 75 ℃,volume ratio of solvent 2-Propanol to furfural 1∶1,volume ratio of solvent to oil ratio 1.5∶1.Under these optimum conditions,the physical properties of recycled oil is listed as follows: viscosity index 119.5,refractive index 1.476 6,Color 1.0,freezing point-15.8 ℃,flash point 218.4 ℃,sulfur content 0.026%,the total oil yield 72.5%. |
