摘要
为探究化工乙醇偶合制备C4烯烃时所需的最佳条件,首先通过Pearson相关系数计算得出相关性系数较强的自变量。然后,使用多元线性回归模型、时间序列预测模型分析不同催化剂组合及温度对化工乙醇偶合制备C4烯烃反应机理的影响,计算模型的结果表明C4烯烃最大收率为48%,此时催化剂组合为:120mg 2wt%Co/SiO_(2)-120mg HAP,化工乙醇投料速率:1ml/min,最佳温度为370℃。最后,基于建立的计算模型,对C4烯烃收率最大化实验进行了拓展。
In order to explore the best conditions required for chemical ethanol coupling and preparation of C4 olefins,the independent variable with strong correlation coefficient is first calculated by Pearson correlation coefficient.Then,multiple linear regression model and time series prediction model were used to analyze the influence of different catalyst combinations and temperature on the reaction mechanism of chemical ethanol coupling.The results of the calculation model showed that the maximum yield of C4 olefin was 48%,and the catalyst combination was:120 mg 2wt%Co/SiO_(2)-120 mg HAP,chemical ethanol feeding rate:1 ml/min,and the optimal temperature was 370℃.Finally,the experiment on maximizing the C4 olefin yield is expanded based on the established computational model.
