Bio-oils, produced by biomass pyrolysis, have become promising candidates for feedstocks of high value-added chemicals and alternative sources for transportation fuels. Bio-oil is such a complicated mixture that contains nonpolar hydrocarbons and polar components which cover almost all kinds of organic oxygenated compounds such as carboxylic acids, alcohols, aldehydes, ketones, esters, furfurals, phenolic compounds, sugar-like material, and lignin-derived compounds. Comprehensive characterization of bio-oil and its subfractions could provide insight into the conversion process of biomass processing, as well as its further utilization as transportation fuels or chemical raw materials. This review focuses on advanced analytical strategies on in-depth characterization of bio-oil, which is concerned with gas chromatography, high-resolution mass spectrometry, FTIR spectroscopy and NMR spectroscopy, offering complementary information for previous reviews.
生物油是通过生物质热解产生的,已成为高附加值化学品原料和替代运输燃料的有前途的候选物。生物油是一种复杂的混合物,包含非极性烃类和极性成分,几乎涵盖了所有种类的有机含氧化合物,如羧酸、醇、醛、酮、酯、糠醛、酚类化合物、糖状物质和木质素衍生化合物。对生物油及其馏分的综合表征可以深入了解生物质加工的转化过程,以及将其进一步用作运输燃料或化学原料的过程。本综述重点介绍了深入表征生物油的先进分析策略,涉及气相色谱、高分辨率质谱、傅里叶变换红外光谱和核磁共振光谱,为以前的综述提供了补充信息。
