Abstract:
“乙醇催化偶合制备C4烯烃”在工业上应用广泛，而影响该反应的重要因素是其催化剂组合及温度，因此研究该反应的工艺条件，对提高C4烯烃生产效率具有重要意义。本文对多组交叉实验数据进行分析，采用控制变量的思想，使用相关系数和多项式拟合得到催化剂组合和温度与乙醇转化率、C4烯烃选择性的关系，并使用多元线性回归模型得到催化剂组合和温度与收率的关系，进而得到使C4烯烃产率最高的最优催化剂组合和最优温度。
“Ethanol catalytic coupling to prepare C4 olefin” has been widely used in industry, and the important factors affecting the reaction are the combination of catalysts and temperature. Therefore, it is of great significance to study the technological conditions of this reaction to improve the production efficiency of C4 olefin. In this paper, sets of cross experimental data are analyzed, by adopting the idea of control variables, using the polynomial fitting and correlation coefficient of catalyst composition and temperature and ethanol conversion rate, the relationship between C4 olefin selectivity, and using multivariate linear regression model to get the relationship between the yield of catalyst composition and temperature, to get the highest production rate of C4 olefin optimal combination of catalyst and the optimal temperature.
