本发明公开的一种醋酸加氢生产乙醇的方法属于醇类物质的生产技术领域,为了解决解决现有技术存在的乙醇生产过程的缺陷,提高乙醇产品品质和降低能耗,发明人特提出了一种醋酸直接加氢为粗乙醇产物,然后依次经过分离出未反应醋酸、脱除酮类组分、分离出醋酸乙酯和脱除水分的工艺过程,获得无水乙醇产品。本发明可有效地分离出醋酸加 A method for producing ethanol by hydrogenation of acetic acid belongs to the technical field of alcohol production. In order to solve the defects of the existing ethanol production process, improve the quality of the ethanol product and reduce the energy consumption, the inventor specially proposes An acetic acid is directly hydrogenated into crude ethanol product, and then the unreacted acetic acid is separated, the ketone components are removed, the ethyl acetate is separated and the moisture is removed, and the anhydrous ethanol product is obtained. The present invention can effectively separate acetic acid
