摘要:
采用热重分析仪对比分析了木质素有无溶剂辅助作用下的热解液化行为,发现添加溶剂有利于木质素的降解,且以丙三醇为溶剂时更利于降解,共溶剂热解液化效果更佳. 通过采用等转化率法及Malek法求得木质素在聚乙二醇、丙三醇辅助热解液化过程中的表观活化能、频率因子和反应机理函数,研究结论有助于后续生物质热解液化机理的深入研究.
Abstract:
In this paper,comparative analyses of the pyrolysis and liquefaction behavior of lignin and lignin in polyhydric alcohols are studied by thermogravimetric analysis. It indicates that the co-solvent pyrolysis process is more beneficial for biomass degradation,and the efficiency is better when using glycerol as solvent. Based on iso-conversional and Malek methods,the apparent activation energy,frequency factor and reaction mechanism functions of lignin co-solvent pyrolysis in PEG400 and glycerol are obtained. The conclusion is helpful to further study on the mechanism of biomass liquefaction in polyhydric alcohols.
