Study on Preparation of Olefins by Coupling ethanol based on partial correlation Analysis and Linear stepwise regression

Abstract

. A correlation analysis was constructed according to the effect of catalyst and temperature on the chemical reaction in the reaction of ethanol coupling to C4 olefin. Firstly, the relationship between the reaction product, temperature, and the reaction product was explored. The chemical mechanism analysis and qualitative image analysis inferred that temperature is related to ethanol conversion and C4 olefin selectivity. Then the Pearson correlation coefficients of each group of temperatures and the corresponding experimental data are calculated, and 90% of the correlation coefficients are greater than 0.9. it is confirmed that they have a significant positive correlation.
