摘要
催化剂组合和温度都会影响乙醇偶合制备C_(4)烯烃的化学反应过程。本文基于2021年全国大学生数学建模竞赛赛题所提供的实验数据,探讨乙醇转化率和C_(4)烯烃选择性的影响因素。首先基于阿伦尼乌斯方程,分别给出了乙醇转换率和C_(4)烯烃选择性与反应温度的指数回归方程模型;接着通过灰色关联分析得出催化剂质量和反应温度是影响乙醇转换率比较重要的因素,而乙醇浓度和反应温度对C_(4)烯烃选择性的影响较大;最后利用高斯过程回归,以C_(4)烯烃收率最高为目的建立优化模型,求得C_(4)烯烃收率的理论最高值为50.07%。
Both catalyst and temperature affect the chemical reaction process of ethanol coupling to produce C_(4) olefin.Based on the experimental data provided by CUMCM,this article discussed the influencing factors of ethanol conversion rate and C_(4) olefin selectivity.Firstly,an exponential regression equation model of ethanol conversion rate and reaction temperature was established based on Arrhenius equation.Then,the grey correlation analysis was used to draw the following conclusions:Catalyst quality and reaction temperature are the most important factors affecting the conversion rate of ethanol,while ethanol concentration and reaction temperature have a greater effect on the selectivity of C_(4) olefin.Finally,using Gaussian process regression,we established an optimization model aimed at the highest yield of C_(4) olefins,and obtained the theoretical maximum yield of C_(4) olefin of 50.07%.
