【摘要】 针对加氢精制润滑油基础油的结构特征 ,对以往氧化安定性关联模型的参数进行了调整 ,弥补了以往模型在预测加氢基础油抗氧化性能方面的不足。建立的 11参数模型能较好地满足不同来源的基础油氧化安定性的预测需要 ,同时模型对碱氮化合物的预测能力也有较大的提高。更多还原

【Abstract】 In order to make up for model deficiency in predicting the oxidation stability of hydrofining lube base oils, the parameters of previous correlate models were adjusted properly according to the structure characteristics of hydrofining lube base oil. The updated eleven-parameter model could meet the needs in predicting the oxidation stability of separate sources base oils. Furthermore, the precision in forecasting the effect of alkaline nitrides was considerably improved.更多还原
