摘　　要：通过对某炼油厂的单一油品和调合油品进行蒸馏试验,利用文献报道的单一油品馏程模型和体积线性加和的方法预测多种油品调合汽油的恩式蒸馏数据;利用LM方法求解上述单一油品模型的参数,并对模型参数进行相关性分析;利用黄金分割法求解调合油品的恩式蒸馏数据,通过对比调合后油品的模型数据和实验数据来验证模型的可预测性。结果表明,模型具有较好的拟合程度,参数具有较高的可信度;恩式蒸馏试验馏程模型预测值与实验值的差值基本在±3℃区间内。因此,可以认为利用该方法预测调合油品的蒸馏数据具有可行性。The Engler distillation data （ASTM distillation） of single gasoline in some refinery were used to predict the ASTM distillation results of blended gasoline by single gasoline distillation model and components linear model. The parameters of the single gasoline model were solved by LM method and their correlations were analyzed. The ASTM distillation data of the blended gasoline were obtained by using golden section method and compared with the experimental data to verify the reliability of the pre- dictive method. Most of the data errors are within ±3℃, indicating the feasibility of this method for prediction of ASTM distillation of blended gasoline.
