The cornstalk and chlorella were selected as the representative of lignocelulosic and algal biomass, and the pyrolysis experiments of them were carried out using pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS). The physicochemical properties of samples and the pyrolytic product distribution were presented. And then the compositional differences between the two kinds of pyrolytic products were studied, the relevant pyrolysis mechanisms were analyzed systematically. Pyrolytic vapor from lignocellulosic biomass contained more phenolic and carbonyl compounds while that from algal biomass contained more long-chain fatty acids, nitrogen-containing compounds and fewer carbonyl compounds. Maillard reaction is conducive to the conversion of carbonyl compounds to nitrogenous heterocyclic compounds with better thermal stability.
玉米秸秆和绿藻分别被选为木质纤维素和藻类生物质的代表,采用热解-气相色谱/质谱联用仪(Py-GC/MS)对它们进行了热解实验。介绍了样品的物理化学性质和热解产物的分布。然后研究了两种热解产物的组成差异,系统分析了相关的热解机理。木质纤维素生物质的热解蒸汽中含有更多的酚类和羰基化合物,而藻类生物质的热解蒸汽中含有更多的长链脂肪酸、含氮化合物和较少的羰基化合物。美拉德反应有利于将羰基化合物转化为热稳定性更好的含氮杂环化合物。
