Abstract

Ethanol coupling to prepare C4 olefin has excellent environmental benefits, economic value and broad application prospects, and has attracted extensive attention from scholars in many research fields at home and abroad. In this paper, based on the collected experimental data generated in the process of ethanol coupling to prepare C4 olefin, statistical analysis method is used to systematically analyze the data information. Firstly, regression models and exponential models of ethanol conversion, selectivity and temperature of C4 olefin were constructed, and the simulation accuracy of the two models under different catalyst combinations was compared by means of goodness of fit, significance probability and residual variance. The results showed that under 16 catalyst combinations, the ethanol conversion rate increased exponentially with the increase of temperature, and under the other 5 catalyst combinations, the ethanol conversion rate increased linearly with the increase of temperature. The selectivity of C4 olefins increased exponentially with the increase of temperature under 11 catalyst combinations, and linearly under the remaining 10 catalyst combinations. Then, based on the statistical data under temperature determination, the statistical distribution of seven different products over time was analyzed, and a multiple regression model was constructed to quantify the relationship between ethanol conversion, C4 olefin selectivity and other five products, and statistical tests were carried out. Finally, a paired sample test model was constructed to quantitatively analyze the effects of catalyst combination and temperature on ethanol conversion and selectivity of C4 olefin.
