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.
