摘要：

This work investigates the thermal degradation of leaves from the Amazon Rainforest litter, which is currently unknown. It formulates innovative thermal degradation equations useful for numerical simulation of wildfires in this biome. Furthermore, this work quantifies for the first time structural and non-structural components of litter leaves, which translates into an improved representation of the thermal degradation process. The main output of this work is the reaction mechanism with six parallel independent reactions for soluble sugars, pectin, hemicellulose, cellulose, lignin, and other organic compounds, which represent the thermal degradation of the litter leaves. The average composition of the Amazonian litter leaves is soluble sugars 22.9%, pectin 9.0%, hemicellulose 18.3%, cellulose 9.1%, lignin 21.2%, and inorganic plus other organic compounds 19.5%. © 2020 Elsevier Ltd
