This paper presents a kinetic analysis of thermal decomposition of olive tree pruning from its basic compounds in pyrolysis and combustion reactions. Experiments were performed by TGA under inert and oxidant conditions and results indicated that the decomposition of the olive tree pruning was related to the material composition. Pseudo-mechanistic models were proposed estimating the yield of pyrolysis on its basic compounds (hemicelluloses, cellulose and lignin). Validity and reliability of the proposed kinetic models were verified by the good fitting between the simulated and experimental curves (with values of R higher than 0.99 in most cases). Moreover, during the fractionation process, an acid fraction was obtained with great fuel properties, a high calorific value and a low residue after its combustion.
本文对橄榄树修剪枝叶在热解和燃烧反应中从其基本化合物进行热分解的动力学进行了分析。实验采用 TGA 在惰性和氧化剂条件下进行,结果表明橄榄树修剪枝叶的分解与材料组成有关。提出了拟动力学模型来估计其基本化合物(半纤维素、纤维素和木质素)的热解产率。通过模拟曲线与实验曲线之间的良好拟合(大多数情况下 R 值高于 0.99)验证了所提出的动力学模型的有效性和可靠性。此外,在分馏过程中,获得了一种具有优异燃料性能、高热值和燃烧后残渣低的酸性馏分。
