摘　　要：以石油破乳剂DPA2 0 3 1为絮凝剂、活性白土为吸附剂 ,经絮凝、吸附再生处理了废柴油。考察了影响絮凝、吸附的各种因素。确定最佳絮凝条件 :温度 80℃、混合时间 45min、10 0g废柴油所需石油破乳剂 2 g ;净化油收率 82 %、透光率 3 9 5 %。最佳吸附条件 :每 10 0 g净化油活性白土用量 15g、硅酸钠 3 g、温度 75℃、时间 40min ;精制油收率 89%、透光率 83 %。Using demulsifier OPA2031 as flocculation agent and activated white clay as an adsorbent, the used diesel oil was regenerated through a two-stepped method, which includes flocculation and adsorption All kinds of factors, which influence the regeneration, were investigated The optimum conditions are: m(demulsifier OPA2031) ∶m(used diesel oil) = 2∶100, temperature:80 ℃,mixing time:45 min in flocculation; m(activated white clay)∶m(sodium silicate)∶m(oil)=15∶3∶100,temperature:75 ℃,mixing time:40 min The regenerated oil is as good as new oil
