我国醋酸产能已严重过剩,而乙醇需求日趋旺盛。醋酸加氢制乙醇技术的研发能同时解决醋酸过剩和乙醇需求的问题。本文介绍了西南院醋酸酯加氢制乙醇的技术进展和工艺路线,阐述了醋酸酯加氢制乙醇工艺流程。该工艺的乙醇生产成本大大低于发酵法乙醇生产成本,经济效益好,具有较好的市场前景。 China’s acetic acid production capacity has been a serious excess, and ethanol demand is growing. Hydrogenation of acetic acid to ethanol technology research and development can solve the problem of excess acetic acid and ethanol demand. This article describes the Southwest Institute of Acetate hydrogenation of ethanol to the technical progress and process route, elaborated acetate hydrogenation process to ethanol. The process of ethanol production costs significantly lower than the fermentation of ethanol production costs, good economic returns, with good market prospects.
