The objective of this study was to identify the pyrolysis of different bio-waste produced by food processing industry in a comprehensible manner. For this purpose, pyrolysis behaviors of chestnut shells (CNS), cherry stones (CS) and grape seeds (GS) were investigated by thermogravimetric analysis (TGA) combined with a Fourier-transform infrared (FT-IR) spectrometer and a mass spectrometer (MS). In order to make available theoretical groundwork for biomass pyrolysis, activation energies were calculated with the help of four different model-free kinetic methods. The results are attributed to the complex reaction schemes which imply parallel, competitive and complex reactions during pyrolysis. During pyrolysis, the evolution of volatiles was also characterized by FT-IR and MS. The main evolved gases were determined as HO, CO and hydrocarbons such as CH and temperature dependent profiles of the species were obtained.
本研究的目的是为了以一种易于理解的方式来确定不同食品加工业生物废料的热解过程。为此，通过热重分析（TGA）结合傅里叶变换红外（FT-IR）光谱仪和质谱仪（MS），对板栗壳（CNS）、樱桃核（CS）和葡萄籽（GS）的热解行为进行了研究。为了给生物质热解提供理论基础，借助四种不同的无模型动力学方法计算了活化能。结果归因于复杂的反应方案，这意味着在热解过程中存在平行、竞争和复杂反应。在热解过程中，挥发物的演化也通过 FT-IR 和 MS 进行了表征。确定了主要的挥发气体为 HO、CO 和烃类，如 CH，并获得了各物种的温度相关分布曲线。
