ABSTRACT

Ethanol has a wide range of molecular sources, outstanding functions and environmental protection. The preparation of C4 olefins by ethanol molecular coupling has a large-scale application direction and economic benefits of sustainable development. In this paper, a corresponding model is established to analyze the catalyst combination factors that affect the preparation of C4 olefins by ethanol coupling. Firstly, all scatter plots between temperature and ethanol conversion rate and scatter plots between temperature and C4 olefin selectivity are made, and nonlinear fitting is carried out. Secondly, the relationship between different catalyst combinations and temperatures on ethanol conversion and C4 olefin selectivity was analyzed, and the fitting equations of different catalyst combinations and temperatures on ethanol conversion and C4 olefin selectivity were obtained by multiple linear regression, thus reflecting the relationship between ethanol conversion, C4 olefin selectivity and each catalyst combination.
