摘要
研究了大庆柴油（250～440℃）中蜡对其低温流动性的影响．结果表明，投点（或冷滤点）与错的组成和含量有关．提出的经验公式能准确地表达投点（或冷滤点）与代油中蜡含量和正构烷烃平均键长之间的定量关系．计算值与实测值吻合．
The influence of wax on low temperature flow properties of Daqing diesel fuel (250 ~ 440 ℃) was studied in deat The experimentai resulfs show that the solid point (or cold filter plugging points) is correlatal with wax conten and composition. The quantitative relation and the solid point (or cold filter plugging point) of usting samples, wax conten and average n- paraffinic chain length could be exactly expressed by the experiential formula presented in the paper. m solid points (or cold filter plugging points) calculated by the experiential formula are correspondence with that actually determined ones in thetest.
