摘要: 提出利用蜡油的密度、折光、分子量、硫含量以及氢含量等5个常规物性预测其13个烃类组成,考察了这些物性的交互作用对烃类组成预测的影响,采用逐步回归方法的得到了较为满意的预测模型。

关键词: 烃类组成, 常规物性, 逐步回归

Abstract: Using 5 normal physical characteristics of the VGO included density、refractive index、molecular weight、the content of sulfur and hydrogen predicte the 13 hydrocarbon types compositions,thinking about the interaction of the 5 factors,Obtained satisfied prediction model using stepwise regression.

Key words: hydrocarbon types composition, normal physical characteristic, stepwise regression
