摘　　要：介绍了共沸精馏法、萃取精馏法、膜分离法和吸附法制备无水乙醇的方法及其研究进展,并评价了各种制备方法的优缺点,阐述了燃料酒精在国内外发展进程,分析了燃料酒精快速发展的原因,介绍了目前燃料酒精生产中需要解决的问题及对策。The methods of producing anhydrous ethanol including azeotropic distillation, extractive distillation, membrane separation and adsorption were introduced briefly in this paper. The advantages and disadvantages of these methods were compared at the same time. Recent application pro- gress of fuel ethanol at home and abroad was also presented. And the reason why this developed so fast was discussed. Finally, the problem and solutions in fuel ethanol production were mentioned.
