摘　　要：研究直馏柴油、催化柴油及加氢精制柴油的组成变化和其润滑性的关系,考察柴油的馏程、90%馏出温度与其润滑性的对应关系。结果表明,催化柴油的润滑性能最好,直馏柴油的润滑性能次之;对于加氢柴油,随着加氢深度增大,柴油抗磨性能变差;柴油中某些能改善其润滑性的组分,多集中在高馏程中;柴油90%馏出温度与柴油润滑性线性相关性较好,柴油中的有效抗磨组分多集中在重组分中,重组分含量增加,柴油的抗磨性能变好。The relationships between changes of constitute ol straight-run distillation diesel, catalyuc diesel oil anu hy- drogenation refining diesel oil with the lubricity were investigated. The corresponding relationships between distillation range,90% distillate temperature and its lubricity of diesel oil were observed. The results show that the lubrication per- formance of catalytic diesel oil is the best, and then is that of the straight-run distillation. As for the hydrogenation diesel oil, along with the depth of hydrogenation increased, the diesel oil anti-wear performance is getting poor. The components which improved the lubricity of diesel oil are more concentrated in the high distillation range. 90% diesel distillate temper- ature has a rather good linear correlation with diesel lubricity. The effective anti-wear components of diesel oil are often concentrated in the heavy components, and with the heavy components content increased, the anti-wear performance of diesel oil is getting better.
