摘　　要：废润滑油是工业生产和交通运输中产生的液体废弃物,具有污染性和资源性的双重特征,通过溶剂精制再生技术可以实现废油的无害化、资源化和可持续化循环利用。文章简述了单一溶剂、组合溶剂、溶剂添加助剂技术再生废润滑油的研究现状,明确了溶剂精制技术再生废润滑油效率高、潜力大、灵活性强等优点,但是存在溶剂种类杂、数量多、再生效果参差不齐等缺点。分析表明通过建立废油再生溶剂“谱系”,采用热力学相平衡理论研究不同“谱系”再生溶剂的溶解能力与选择性规律,可建立筛选兼具溶解力与选择性再生溶剂的理论方法,为促进和发展我国溶剂精制再生废油技术提供理论指导和技术支撑。Used lubricating oils(ULOs)are waste liquids produced in industrial production and transportation,which are pollutants and also resources.ULOs can be sustainably recycled through innocent treatment and resource recovery with the regeneration technology by solvent extraction.The research progress in ULO regeneration technology with single solvent,combined solvent,and solvent additives was expounded in this paper.It is found that the ULO regeneration technology by solvent extraction is advantageous for high efficiency,exciting potential,and strong flexibility,but disadvantageous for too many types and quantities of solvents,and varied regeneration performances.By creating a“spectrum”of solvents for ULO regeneration,a theoretical method screening the solubility and selectivity of regeneration solvents can be established by studying the law of solubility and selectivity of solvents in different“spectrum”series with the thermal phase equilibrium theory,to provide theoretical guidance and technical support for promoting and developing the ULO regeneration technology by solvent extraction in China.
