The experimental data of catalyst reaction performance, ethanol yield, reaction rate, reaction activation energy, reaction mechanism and other data were obtained under certain conditions by using a fixed bed reactor. The reaction kinetics characteristics and reaction mechanism of the catalyst were obtained by calculation and analysis.The experimental results show that the ethanol yield of Cu-ZnAl2O3 catalyst is closely related to reaction temperature and hydrogen flow rate. With the increase of temperature and hydrogen flow rate, the ethanol yield also increases accordingly. In terms of reaction rate, with the increase of reaction temperature, the reaction rate also increases. The reaction activation energy is between 170-190 kJ/mol, indicating that the reaction has certain thermodynamic control. In terms of reaction mechanism, the reaction mechanism and 精品文档---下载后可任意编辑rate-determining step were obtained by analyzing the reaction products and intermediates.This study provides new experimental data and theoretical basis for a deeper understanding of the reaction of ethanol production by acetic acid indirect hydrogenation, and also provides reference for catalyst design and optimization.Keywords: Cu-ZnAl2O3 catalyst; acetic acid indirect hydrogenation for ethanol production; intrinsic kinetics; reaction mechanism
