摘　　要：以两种表面活性剂作絮凝剂、活性白土为吸附剂 ,经絮凝、吸附再生处理了废润滑油。考察了影响絮凝、吸附的各种因素。确定最佳絮凝条件 :温度 85°C、1 5 0 g废润滑油所需两种絮凝剂用量分别为 3.7g和 1 .3g;最佳吸附条件 :活性白土 1 2 .3%、温度 1 1 0°C、时间 90 min。经元素分析 ,净化精制后油品的 Zn、Pb、Ca、P等元素的含量显著降低。精制油理化指标符合国家标准。Using two kinds of surfactants as flocculation agents and activated white clay as an adsorbent, the used lubricating oil was regenerated through a two stepped method, which includes flocculation and adsorption. Factors influencing the regeneration were investigated. The optimum conditions are: m (surfactant 1): m (surfactant 2): m (used lubrincating oil)=3.7∶1.3∶150; flocculation temperature 85 °C m (activated white clay)∶ m (oil)= 12.3 ∶100, adsorption temperature, 110 °C ; mixing time, 90 min. The content of N,P,Pb,Zn in the regenerated oil is significantly less than that in the used oil, and the regenerated oil is as good as new oil.
