This study aims at investigating physicochemical properties and pyrolysis kinetics of hazelnut husk, an abundant agricultural waste in Turkey. The physicochemical properties were determined by bomb calorimeter, elemental analysis and FT-IR spectroscopy. Physicochemical analysis results showed that hazelnut husk has a high calorimetric value and high volatile matter content. Pyrolysis experiments were carried out in a thermogravimetric analyzer under inert conditions and operated at different heating rates (5, 10, 20°C/min). Three different kinetic models, the iso-conversional Kissinger-Akahira-Sunose (KAS) and Ozawa-Flynn-Wall (OFW) models and Coats-Redfern method were applied on TGA data of hazelnut husk to calculate the kinetic parameters including activation energy, pre-exponential factor and reaction order. Simulation of hazelnut husk pyrolysis using data obtained from TGA analysis showed good agreement with experimental data. Combining with physicochemical properties, it was concluded that this biomass can become useful source of energy or chemicals.
本研究旨在研究土耳其丰富的农业废弃物榛子壳的物理化学性质和热解动力学。通过量热计、元素分析和傅里叶变换红外光谱（FT-IR）对其物理化学性质进行了测定。物理化学分析结果表明，榛子壳具有高热值和高挥发分含量。在热重分析仪中，在惰性条件下以 5、10、20°C/min 的不同加热速率进行了热解实验。应用三种不同的动力学模型，即等转化率 Kissinger-Akahira-Sunose（KAS）和 Ozawa-Flynn-Wall（OFW）模型以及 Coats-Redfern 法，对榛子壳的 TGA 数据进行了处理，以计算动力学参数，包括活化能、指前因子和反应级数。使用 TGA 分析获得的数据对榛子壳热解进行模拟，结果与实验数据吻合较好。结合物理化学性质，可以得出结论，这种生物质可以成为有价值的能源或化学品来源。
