摘　　要：综述了近10年来国内外研究中用基团贡献法预测石油馏分汽液平衡工作的进展情况.重点介绍了UNIFAC与CORGC模型和石油馏分的基团划分方法以及预测效果.并简要论述了石油馏分基团组成的几种模拟计算方法,回顾了分子型模型的应用情况。This paper reviews the achievements of the research on prediction of VLE for petroleum fractions with group-contribution method during the last decade. The UNIFAC-VLE model and CORGC-EOS are briefly described. Some methods for estimating the group composition of an oil cut are discussed.
