Abstract:

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 predictive method. Most of the data errors are within ±3 ℃, indicating the feasibility of this method for prediction of ASTM distillation of blended gasoline.

Key words: gasoline blending, distillation model, LM, golden section
