Coal indirect liquefied diesel soot (Fischer-Tropsch synthesis diesel soot, F-T DS) was collected by burning coal indirect liquefied diesel (F-T Diesel) with a self-made soot trap device in the laboratory. F-T DS was modified with oleylamine modification method to obtain oleylamine modified F-T DS (F-T DS-OLA). The effect of 10^# white oil with F-T DS or F-T DS-OLA on the lubrication performance was investigated using a long-time four-ball friction and wear tester. The composition, structure, morphology and tribological mechanism for F-T DS and F-T DS-OLA had been studied by using FTIR, XPS, Raman, XRD and other instruments. The results show that F-T DS modified by oleylamine can increase lipophilic groups. The average particle size of F-T DS and F-T DS-OLA are 64 nm and 38 nm respectively. The main structure component is amorphous carbon with a small amount of graphite crystallites. The average friction coefficient (AFC) first decreases and then increases as the mass fraction of F-T DS and F-T DS-OLA increases in 10^# white oil. When the mass fraction of F-T DS is 0.6 wt%, the AFC reaches the minimum, and the AFC reaches the minimum when the mass fraction of F-T DS-OLA is 0.8 wt%. The average wears scar diameter (AWSD) of the steel ball also decreases first and then increases. F-T DS reaches the minimum at 0.6 wt%, and F-T DS-OLA reaches the minimum at 0.8 wt%. Comprehensive AFC and AWSD analysis, the antifriction and anti-wear effect of F-T DS is greatly improved after oleylamine modified. Through the analysis of the surface morphology of the upper ball wear scar and valence state of the surface elements, it can be obtained that the wear scar of the upper test ball becomes shallow after adding F-T DS-OLA. A lubricating film containing C, O and iron oxides is formed on the surface, which can improve the antifriction and anti-wear effects of 10^# white oil.

通过在实验室使用自制的煤烟捕集装置燃烧煤间接液化柴油（FT柴油）来收集煤间接液化柴油烟灰（Fischer-Tropsch合成柴油烟灰，FT DS）。用油胺改性方法对FT DS进行改性，得到油胺改性的FT DS（FT DS-OLA）。效果10 ^＃使用长时间的四球摩擦磨损测试仪研究了具有FT DS或FT DS-OLA的白油对润滑性能的影响。利用FTIR，XPS，Raman，XRD等仪器对FT DS和FT DS-OLA的组成，结构，形貌和摩擦机理进行了研究。结果表明，油胺改性的FT DS可以增加亲脂性基团。FT DS和FT DS-OLA的平均粒径分别为64 nm和38 nm。主要结构成分是具有少量石墨微晶的无定形碳。在10 ^＃中，随着FT DS和FT DS-OLA的质量分数增加，平均摩擦系数（AFC）首先减小，然后增加白油。当FT DS-OLA的质量分数为0.6重量％时，AFC达到最小值，并且当FT DS-OLA的质量分数为0.8重量％时，AFC达到最小值。钢球的平均磨损疤痕直径（AWSD）也先减小然后增大。FT DS达到最小值，为0.6 wt％，FT DS-OLA达到最小值，为0.8 wt％。全面的AFC和AWSD分析，油胺改性后，FT DS的减摩和抗磨效果大大提高。通过分析上部球的磨损痕迹和表面元素的价态，可以看出加入FT DS-OLA后上部测试球的磨损痕变得浅。在表面形成含有C，O和氧化铁的润滑膜，可以改善10的抗磨和抗磨效果^＃白油。
