柴油正构烷烃含量与其低温性质关系研究

INFLUENCE OF N-ALKANE ON CRYOGENIC CHARACTER OF DIESEL OIL

摘要: 以孤岛原油和大庆原油为原料，采用实沸点蒸馏工艺得到不同馏分段组成的一系列柴油样品。通过测定柴油的低温性质（浊点、冷滤点和凝点）和利用气相色谱测定从C12到C25正构烷烃的含量，研究了各正构烷烃含量对柴油低温性质的影响。并利用多元回归拟合建立了关于柴油低温性质与其正构烷烃含量之间的数学模型。

Abstract: A series of diesel oil with different fractions are got from the crude oil of Daqing and Gudao by real-boiling point distillation. Cryogenic characters of diesel oil: cloud point, cold filter plugging point, condesation point are got at the same time.The
