摘要:

生物炼制是新时代应对能源危机和环境污染的极佳策略,基于生物炼制可以将低值的生物质资源转化为各类高附加值产品。糠醛是一种来自生物质资源的高附加值平台化合物,在能源、医药、化工等领域具有重要应用。糠醛的工业生产已经近一个世纪,工业生产技术已经比较成熟,但是目前工业生产过程中还存在不少问题。为解决糠醛工业生产中存在的问题,研究者对制备糠醛的新技术和新工艺进行了研究与探索。本文首先介绍了糠醛的性质及应用,分析了糠醛的工业生产技术现状和所面临的问题,如利用无机酸作催化剂时会腐蚀设备,催化剂不易回收,存在污染水源等问题。然后详细叙述了水解法和热解法制备糠醛的技术研究现状以及微波加热辅助新工艺的特点,最后展望了糠醛制备技术的未来发展方向。

Abstract:

Biorefinery is an excellent strategy to deal with the energy crisis and environmental pollution in the new age. Based on biorefinery, low-value biomass resources can be converted into various value-added products. Furfural is one value-added platform chemical from biomass resources, which has important applications in energy, medicine, chemical, and other fields. The industrial production of furfural has come out for nearly one century and is relatively mature nowadays. However, there are still some issues remain to be solved in the industrial production. In order to solve these problems, efforts have been paid on exploring new technologies and progresses. In this paper, the characteristics of furfural were introduced firstly, and the present situation and problems of furfural industrial production technology are summarized, including corrosion of equipment caused by acid catalysts, difficulty in catalyst recycling, water pollution and so on. Then, the research status and problems of furfural preparation by hydrolysis and pyrolysis and the characteristic of the microwave-assisted technology were carefully reviewed. Finally, the future development direction of furfural preparation technology was prospected.

Key words: biomass, furfural, platform compound, hydrolysis, pyrolysis
