Abstract

The article presents the results of a study of some regularities of the process of catalytic oxidation in the gas phase of methanol to formic acid. To do this, first, experiments were carried out on a unique laboratory setup at the nodal values of the initial parameters, and then a multiple regression equation for the process was created, the coefficients of the equation were calculated and their significance was determined. The adequacy of the equation was checked and a more sensitive parameter was identified. Using Fisher's criterion, the statistical significance of the equation was proved. Statistical analysis of the obtained regression equation was carried out: checking the significance of the equation and its coefficients, studying the absolute and relative errors of approximation. Paired correlation indicators of the equation coefficients are also calculated. Based on the maximum correlation coefficient, it was concluded that changes in the temperature of the reaction medium have the greatest effect on the yield of formic acid. It was also found that the parameters of the model are statistically significant. Keywords: methanol, formic acid, catalytic oxidation, regression equation, pair correlation.
甲醇催化气相氧化制甲酸过程规律研究
本文对甲醇气相催化氧化制甲酸过程的一些规律进行了研究。为此,首先在一个独特的实验室装置上,以初始参数的节点值进行实验,然后建立该过程的多元回归方程,计算方程的系数并确定其显著性。检查了方程的充分性,并确定了一个更敏感的参数。利用Fisher准则,证明了方程的统计显著性。对得到的回归方程进行统计分析:检验方程及其系数的显著性,研究近似的绝对误差和相对误差。并计算了方程系数的成对相关指标。由最大相关系数可知,反应介质温度的变化对甲酸产率的影响最大。还发现模型的参数具有统计显著性。关键词:甲醇,甲酸,催化氧化,回归方程,对相关
