摘　　要：高温热解动力学模型的建立有助于将生物质转化为不含有焦油的高价值产品。在本文的研究中选取稻壳和秸秆作为研究对象,通过热重–质谱联用分析热解过程,使用非等温法计算了高温热解动力学参数。发现在高温时固体残留物中氧含量出现了二次快速下降,至900℃后保持相对稳定。随后进一步改进了CRECK生物质热解详细动力学模型。修正了高温条件下含氧固体转化机制,通过实验结果以及收集了大量文献中的实验数据验证了模型的准确性。The development of a high-temperature pyrolysis kinetic model is instrumental in converting biomass into valuable products without tar formation.This study focuses on rice husks and straw as research subjects.Utilizing thermogravimetry-mass spectrometry coupling(TGA-MS),the pyrolysis process was analyzed,and high-temperature pyrolysis kinetic parameters were calculated through a non-isothermal method.It was observed that the oxygen content in the solid residue experienced a rapid decrease for the second time at high temperatures,stabilizing after reaching 900℃.Additionally,the CRECK biomass pyrolysis detailed kinetic model was refined to enhance accuracy.The conversion mechanism of oxygen-containing solids under high-temperature conditions was corrected.The model's precision was validated through experimental results and a comprehensive compilation of experimental data from the literature.
