Catalyst combination and temperature will have a certain impact on the selectivity and yield of C4 olefins. This paper first analyzes the relationship between the products and the reaction mechanism, so as to find out the main products. Then, according to the time-varying trend, regression analysis is carried out. The specific expression and error are obtained by solving the correlation results of the products with strong significance, and the relevant conclusions are obtained by qualitative analysis of the results of the products with weak significance. Then the specific catalyst combination is inferred by distance discrimination method. Finally, the grey correlation analysis is used to verify the curve fitting results in the above two questions.
