ABSTRACT

In this paper, according to different conditions, establish the corresponding model to fit the data, analyze the data results to find the relationship between independent variables and dependent variables, and study the relationship between substances in the chemical reaction[1]. First of all, the linear correlation between data is not high through Pearson coefficient calculation, and the use of linear calculation has a large error, so it is not reference. Then a nonlinear regression model was established, and the relationship between ethanol conversion, C4 olefins selectivity and temperature was obtained by using exponential function fitting data. Finally, according to TOPSIS method, the similarity with the ideal scheme is used as the basis to obtain the optimal solution and the worst solution.
