摘　　要：渗透汽化优先透醇膜分离技术用于燃料乙醇的浓缩分离,可以有效解决燃料乙醇生产中的产品抑制问题,有望实现燃料乙醇的连续化生产,因此渗透汽化优先透醇膜的研究受到世界范围内的广泛关注。本研究在简单介绍渗透汽化优先透醇膜研究背景的基础上,对近二十年来国内外渗透汽化优先透醇膜及膜材料的研究进展进行了详细介绍,并对其发展前景做出了展望。Ethanol permeselective membranes by pervaporation were used for ethanol recovery from fermentation broth, which could resolve product inhibition problem effectively and was expected to realize the continuous production of ethanol fuel. Study on the membranes by pervaporation has been received extensive attention in the world. Based on a brief introduction of investigation background in ethanol permselective membranes, the worldwide research progress of the materials in recent 20 years was presented in detail. Moreover, the foresight of the membranes was also brought forward.
