摘要:

粗甘油是生物柴油生产过程的副产品,对其进行绿色处理和应用已成为迫切研究的课题。本文分类介绍了粗甘油生物、化学和电化学转化方法的研究现状。在此基础上分别对粗甘油通过生物转化方式生产1,3-丙二醇、氢气等化学品,利用化学转化方式生产丙烯醛和聚氨酯高分子材料和电化学转化方式制备燃料电池的研究现状进行了综述,并分析了粗甘油高值化利用研究及发展趋势。粗甘油生物转化存在培养基成本较高、产物分离困难等不足,限制了目前的工业化应用;化学转化方式还处于初期研究阶段;电化学转化方式作为新兴技术,具有良好的发展空间。本文指出粗甘油可以作为一种新型的生物质资源,粗甘油基化学品与新材料的开发研究具有广阔的发展前景。

Abstract:

Crude glycerol is the by-product of the biodiesel production, and its green treatment and application have become an urgent research topic. This paper introduces the research status of biological, chemical and electrochemical conversion methods of crude glycerol. On this basis, the research status of the production of 1,3-propanediol and hydrogen from crude glycerol by bioconversion, the production of acrolein and polyurethane by chemical conversion and the preparation of fuel cell by electrochemical conversion are reviewed, respectively. The research and development trend of high-value use of crude glycerol are also analyzed. Crude glycerol bioconversion has the disadvantages of the high cost of the culture medium and difficulty in product separation, which limits the current industrial application. Meanwhile, chemical conversion methods are still in the initial research stage, whereas electrochemical conversion methods have a good development space as emerging technologies. This paper points out that crude glycerol can be used as a new type of biomass resource, and the research of crude glycerol-based chemicals and new materials have broad prospects for development.

Key words: crude glycerol, high-value utilization, bioconversion, chemical conversion, electrochemical conversion
