Research on the Optimization Model of Ethanol Coupling to C4 Olefins Based on Regression Analysis

China is mainly prepared with fossil raw materials, C4 olefin, ethanol is a good raw material for the preparation of low-carbon olefins, but due to the preparation of ethanol coupling, the reaction principle of C4 olefins is more complicated, and a lot of research has not been invested in China, on this basis, the comprehensive use of BP neural network, genetic algorithm, orthogonal test and other methods, combined with SPSSpro, MATLAB and other software to process the data, explore the influence of catalyst combination and temperature on C4. Olefin yield. The results showed that when the Co load was 2 wt%, the Co/SiO2 content was 120 mg, the HAP content was 200 mg, the ethanol concentration was 2.1ml/min and the temperature was 400, the yield of C4. Olefin was about 62%. The obtained ethanol coupling preparation, the optimal control scheme of C4. Olefins is more efficient, can effectively promote the production of C4 olefins, in order to make up for the traditional preparation, C4 olefins shortcomings. And it can provide additional researchers with certain ideas.
