摘要抽出油是润滑油溶剂精制装置生产过程中的一种副产物，因富含大量芳烃、部分饱和烷烃和少量胶质、沥青质，使其直接加工利用受到限制，常作为燃料油的调和组分，经济效益低。为提高抽出油的利用价值，对其进行处理后进一步加工利用，包括：炼油装置掺炼，调和道路沥青，制备表面活性剂，生产橡胶填充油、溶剂油、导热油、绝缘油和缩合多环芳烃树脂，对抽出油的综合利用前景进行了展望。

process . The processing and utilization of extract oil was limited and used as blending component of fuel oil because of high content of aromatic , small amount of saturated alkane , colloid and asphaltene. Therefore, the economic benefit is low . In order to improve the utilization value of extract oil , it can be further processed and used after treatment , including blending extract oil into feedstock of refinery units, blending paving asphalts, preparing surfactant, producing rubber filling oil, solvent oil, heating oil , insulating oil and condensed polynuclear aromatic resin . The comprehensive utilization prospect of extract oil was prospected.

溶剂精制工艺是润滑油基础油生产中的一种传统
工艺，主要有糠醛溶剂精制、苯酚溶剂精制和N-甲基吡略烷酮(NMP)溶剂精制。在美国.苯酚精制基本上已被淘汰，大部分溶剂精制装置采用NMP作溶剂,其
余主要采用糠醛；在我国，采用糠醛作溶剂的装置处理能力约占总处理能力的80%其余则采用苯酚，只有个别装置采用NMP[1-2]。润滑油溶剂精制主要是利用溶剂脱除基础油中的多环短侧链芳烃、含硫、含氮、含
