C4 olefins are widely used in the production of chemical products and pharmaceutical intermediates. Ethanol as a clean energy, the preparation of C4 olefins can protect the environment. Here we mainly study the specific effects of catalyst combination and temperature on the degree of reaction. In this paper, we first draw each group of data on a layer in order to observe the properties of the whole, and then use the mean method to find a curve that can represent the characteristics of the whole. The correlation analysis of the curve is carried out, and then it is known that the effect of temperature on the degree of reaction has a sinusoidal relationship through the reference literature, which is further expressed by mathematical formula. When analyzing the experimental results, we focus on the change of the data, whether it has gone through the extreme value, the relationship between the reaction rate and the formation rate and so on. After the improvement of the model, the thermodynamic formula and kinetic formula were used to study the conversion rate of ethanol and the selectivity of C4 olefins. Finally, it is concluded that the relationship between ethanol conversion and temperature is proportional and has a strong correlation, and the selectivity of C4 olefins is proportional to temperature, but the correlation is moderate; at 350 degrees, the test results of a given catalyst combination at different times of an experiment are analyzed in three aspects.
