全球气体膜分离技术的研究和应用趋势——基于近20年SCI论文和专利的分析

On the research and application trends of global gas membrane separation technology ——Based on analysis of SCI articles and patents in recent 20 years

为把握整体气体膜分离产业研究和创新状况,在Web of Knowledge(WOK)平台的Web of Science®数据库和Derwent(德温特)专利数据库检索了有关气体膜分离技术的文献,并采用文献计量学的方法进行分析。结果表明,1995—2014年全球相关论文共2972篇,专利4266项。气体膜分离技术现处于研究的成长期,已形成核心作者群。气体膜分离材料的研究热点为混合基质膜、沸石膜和炭膜,但工业化应用以传统有机高分子材料为主,气体膜分离技术主要的研究和应用领域为氢回收、空分和脱碳。美国和日本的研究和应用优势较明显,我国气体膜分离的研发主体为高校和科研院所,尽管发文量位居世界第二,但科研质量和国际影响力仍需提高,科研成果转化率不高。预计未来气体膜分离的研究重点会在沸石膜和炭膜等新型膜材料的空间结构的设计合成和碳捕获的技术应用上,渗透汽化膜的应用和挥发性有机物(VOCs)分离也是未来的研究方向。

To grasp the whole research and innovation of gas membrane separation industry,we searched the literature of gas membrane separation in the web of science database and Derwent patents database. The results show that 2972 articles and 4266 patents with relevance were published during 1995-2014. The research of gas membrane separation is in its growth period with established core authors. The research is focused on the new membrane materials including mixed matrix membranes,zeolites membranes and carbon membranes. But the traditional polymer materials are still widely used in industry. Hydrogen recovery,air separation and carbon removal are the main areas of the research and application of gas membrane separation. The lead of US and Japan on the research and application is obvious. Most researches in China are done in colleges and institutes. Although the number of the published articles from China rankes the second in the world,the quality and influence of research still need to be improved. It can be predicted that design of space structure of new membrane materials,such as zeolite membrane and carbon membrane,will be the research hotspot on gas membrane separation in the future. Also,the research will focus on the application of pervaporation and the separation of volatile organic compounds（VOCs）.
