石油产品吸氧安定性能研究与评价──Ⅱ柴油吸氧氧化中物化性质的变化

Study and Evaluation of Oxygen Absorption Stable Performance of Petroleum Products ──Ⅱ Study on Physicochemical Properties of Diesel Fuels in Oxygen Absorption

本文详细考察了大庆直馏和焦化加氢柴油在吸氧氧化中物化性质随吸氧量的变化．实验结果表明，随吸氧量的增加，柴油的酸度和戊烷不溶物含量增加，颜色变深．本文提出的吸氧安定性因子能够准确反映出不同种类柴油在吸氧安定性能方面的差别，可用以评价柴油的吸氧安定性能．

The changes of physicochemical properties of Daqing straight run and hydrogenated coking diesel in the oxygen absorption were investigated.The experimental results show that the acidities and the nounal pentane insolubles of the died fuels increase rapidly and the colors darken gradually with the increasing of oxygen quantities absorbed by the died fuels. The difference in oxygen absorption stable performances of different diesel fuels can be accurately and easily seen by the oxygen absorption stable index presented in this paper and the oxygen absorption stable index can be ed to evaluate the oxygen absorption stable performances of diesel fuels.
