To evaluate the potential of compost based on municipal solid waste (MSW) and 20% legume pruning under a pyrolysis process, generated products, including solids (biochar), liquids (bio-oil), and gases (non-condensable gases), through experimentation in a pilot plant with a fluidized bed reactor at 450°C and gas chromatography/mass spectrometry have been analysed. In addition, the compost kinetic behaviour by thermogravimetric analysis (TGA), using the Flynn-Wall-Ozawa (FWO) method, has been investigated. Four different reaction zones, associated with lignocellulosic materials (hemicellulose, cellulose, and lignin) with a first step for water evaporation, in TGA curve have been observed. A biochar with low stability and aromaticity, considering high and low O/C and H/C ratios, respectively, has been obtained. The obtained pyrolytic liquids contain a high concentration of phenolic compounds because of a significant presence of lignins and other high molecular weight compounds in the original material. Moreover, the generated non-condensable gases consist mainly of short-chain compounds, such as alcohols, aldehydes, and alkenes produced from hemicellulose, cellulose, and proteins.

城市固体废物堆肥的热解：作为废物管理可持续实践的中试工厂评估。

为了评估基于城市固体废物 (MSW) 和 20% 豆类修剪物在热解过程中的堆肥潜力，生成的产品包括固体（生物炭）、液体（生物油）和气体（不凝性气体），通过对在 450°C 的流化床反应器中进行的实验和气相色谱/质谱分析进行了分析。此外，还利用弗林-沃尔-小泽（FWO）方法通过热重分析（TGA）研究了堆肥动力学行为。在 TGA 曲线中观察到与木质纤维素材料（半纤维素、纤维素和木质素）相关的四个不同的反应区，第一步是水蒸发。分别考虑高和低O/C和H/C比，获得了具有低稳定性和芳香性的生物炭。由于原始材料中大量存在木质素和其他高分子量化合物，所得热解液体含有高浓度的酚类化合物。此外，产生的不凝性气体主要由短链化合物组成，例如由半纤维素、纤维素和蛋白质产生的醇、醛和烯烃。
