Abstract Pyrolysis of more biomass group components should be studied in order to obtain a more comprehensive understanding of various biomass pyrolysis. In this study, chemical properties of six biomass group components, namely, starch, cellulose, Hemicellulose (Hem), lignin, protein and oil, were evaluated and their pyrolysis behavior, gaseous product evolution, kinetics and product distributions were investigated using TG-FTIR and Py-GC/MS. The results indicated that their devolatilization sensitivity to heating rate followed the order of Hem > starch > oil > cellulose ≈ protein > lignin. Kinetic results revealed that it was difficult to pyrolyze for biomass rich in oil and lignin but easy to pyrolyze for biomass rich in cellulose, starch, Hem and protein. During their pyrolysis, polysaccharides (starch, cellulose and Hem) mainly generated oxygen-containing components such as C O and O-heterocycles; lignin mainly contributed to the formation of phenols (up to 81.4%); protein produced nitrogen-containing components (up to 52.71%), including N-heterocycles, pyrroles, pyridines, nitriles, and amines/amides; oil generated large quantities of alkenes (46.48%). Finally, this research would serve to gain further insight into biomass pyrolysis containing different group components.

淀粉、纤维素、半纤维素、木质素、蛋白质和油类六类生物质的热解行为及产物分布

摘要 为了更全面地了解各种生物质热解，应研究更多生物质组组分的热解。在这项研究中，评估了六种生物质组成分，即淀粉、纤维素、半纤维素 (Hem)、木质素、蛋白质和油的化学性质，并使用 TG-FTIR 研究了它们的热解行为、气态产物释放、动力学和产物分布和 Py-GC/MS。结果表明，它们的脱挥发分对加热速率的敏感性遵循以下顺序：Hem>淀粉>油>纤维素≈蛋白质>木质素。动力学结果表明，富含油和木质素的生物质难以热解，而富含纤维素、淀粉、Hem和蛋白质的生物质易于热解。在热解过程中，多糖（淀粉、纤维素和Hem)主要生成CO和O-杂环等含氧组分；木质素主要有助于酚类的形成（高达 81.4%）；蛋白质产生的含氮成分（高达 52.71%），包括 N-杂环、吡咯、吡啶、腈和胺/酰胺；石油产生大量烯烃（46.48%）。最后，这项研究将有助于进一步了解含有不同组成分的生物质热解。
