The pyrolysis behavior of Turkish biomass samples such as hazelnut shell, almond shell, and sunflower stalk residue was studied using a thermogravimetric analysis (TGA) laboratory-scale setup. Biomass samples were characterized using the standard method of the Van Soest detergent analysis, and both the virgin biomass and fractions were investigated. The reaction temperature was increased to 900 °C with a heating rate range between 2 and 60 °C min⁻¹ in the TGA experiments. Seven solid-state reaction models were applied to evaluate the obtained experimental TGA results. The heating rate was not the only parameter affecting the values of activation energy and the ratio of the main components such as the cellulose and lignin of the virgin biomass samples (almond shell, sunflower stalk, and hazelnut shell) also affected the value of the activated energy values. It was determined that a model fitting mechanism gives limited information to determine the exact activation energy values for the samples. The reaction order model provided straightforward and decisive results for all the biomass and lignin samples. Models of two- and three-dimensional diffusion were better suitable for the cellulose devolatilization. It was also determined that the activation energy of the lignin samples was similar regardless of the types of biomass. According to the kinetic calculations, the cellulose samples showed the highest activation energy values and the lignin samples had the lowest.

使用热重分析（TGA）实验室规模的装置研究了土耳其生物质样品（如榛子壳，杏仁壳和向日葵茎残渣）的热解行为。使用Van Soest去垢剂分析的标准方法对生物质样品进行表征，并对原始生物质和馏分进行了研究。反应温度以2至60°C min ^-1的升温速率升高至900°C在TGA实验中。七个固态反应模型用于评估获得的实验TGA结果。加热速率不是影响活化能值的唯一参数，原始生物质样品（杏仁壳，向日葵茎和榛子壳）中主要成分（如纤维素和木质素）的比率也影响活化值能量值。已确定模型拟合机制给出的信息有限，无法确定样品的确切活化能值。反应顺序模型为所有生物质和木质素样品提供了直接而决定性的结果。二维和三维扩散模型更适合于纤维素脱挥发分。还确定了木质素样品的活化能是相似的，而与生物质的类型无关。根据动力学计算，纤维素样品显示出最高的活化能值，而木质素样品具有最低的活化能值。
