【摘要】 采用两段式溶剂精制工艺,进行溶剂精制工艺改善的实验研究。在最佳工艺条件下回收的废内燃机油的粘度指数为104.61,折光率为1.4594,色度为1.0,符合润滑油基础油的HVI标准。回收后的油品经添加适当的添加剂调和后可作为成品润滑油继续使用。更多还原

【Abstract】 A experiment research was carried on for solvent refining using the two-segment solvent refining technics .Under the optimal technology conditions,the properties of the recovered oil were viscosity index at 104.61,refractive index at 1.4594,colourity at 1.0.According to this result,the recovered oil could reach the HVI standard of base oil.And the recovered oil could be used as finished lubricating oil by harmonicing of proper quantities additions.更多还原
