摘要
用加压差示扫描量热法(PDSC)研究了煤转化的基础油(CTL)和Ⅲ类油以及Ⅳ类油(PAO)的氧化安定性,并考察了3种基础油对抗氧剂的感受性。结果表明CTL基础油的氧化安定性和Ⅲ类油接近,但是比Ⅳ类差。3种基础油对胺类抗氧剂(AO)的感受性相近,但Ⅳ类油的感受性最好。由煤转化而成的CTL基础油有可能成为Ⅲ类基础油的替代品。
The oxidation stability of coal-to-liquid(CTL)base oil,group Ⅲ and group Ⅳ base oil was studied by the method of pressurized differential scanning calorimetry through contrast researches.The effects of anti-oxidants were investigated.The results indicate that oxidation stability of CTL base oil is similar to group Ⅲ base oil,and lower than group Ⅳ base oil.The three base oils have similar effects on antioxidant(AO).The coal-to-liquid(CTL)base oil may become the substitute of group Ⅲ base oil.
