With the rapid development of modern science and technology, C4 olefins are widely used in the production of chemical products and pharmaceutical intermediates. Energy supply presents a trend of diversification. Among many new energy sources, ethanol is the ideal raw material for the production and preparation of C4 olefin. It is of great practical significance and economic value to explore the technological conditions for the preparation of C4 olefin by ethanol catalytic coupling. Aiming at the research on question B of the National College Students’ mathematical modeling competition of the higher education society cup in 2021, based on the given groups of experimental data, In this paper, ethanol was used as platform compound and Co/SiO2-HAP catalyst was used as catalyst. Based on the given experimental data, Kriging proxy model was constructed. Finally, EGO optimization algorithm was used and numerical calculation was performed by MATLAB program-ming to obtain the optimal technological conditions for the preparation of C4 olefins by ethanol cat-alytic coupling. Moreover, the mathematical model constructed in this paper can be used to obtain the best experimental scheme through optimization calculation, thus greatly reducing the number of experiments and saving costs.
