The invention discloses a method for constructing an industrial knowledge graph in a fuel ethanol fermentation process, and belongs to the field of intelligent manufacturing in an industrial biological fermentation process. The method comprises three stages: firstly, collecting data of a liquefaction process, a distiller's yeast process and a fermentation process in a fuel ethanol production process, constructing and optimizing a prediction model of a tank outlet ethanol volume ratio according to the collected data, and preliminarily screening the important characteristics influencing the fuel ethanol production process according to the model; then searching for variables having obvious causal relationship with the features in a superior production stage based on the features until all variables in compliance with conditions in each production stage are found out; and finally, presenting the found key variables and the causal relationship degrees among the key variables in a knowledge graph form. 本发明公开了一种燃料乙醇
