摘　　要：提出用正构烷烃模型分子法进行石油馏分的基团划分，只需平均沸点一个物性参数，即可简捷方便地确定假组分的基因组成。将此法与ＵＮＩＦＡＣ基团贡献法相结合，预测了大庆、辽河＜３５０℃馏分油的常压气液平衡，并与试验值和ＳＲＫ模型预测值进行了对比。The group composition of a pseudo-component molecule can be determined by thenormal paraffin model molecule method which only needs one physical property (average boiling point). Incombination with the UNIFAC group contribution model, it was applied to predict the vapor-liquid equilibrium for < 350 ℃ fractions from Daqing and Liaohe crude oils at atmospheric pressure. The calculated results were compared with the experimental data and the prediction data from SRK equation of state aswell.
