Exothermicity during the pyrolysis of large wood particles

Image
  Exothermicity during the pyrolysis of large wood particles Understanding Exothermicity During the Pyrolysis of Large Wood Particles Pyrolysis is a thermochemical decomposition process of organic materials in the absence of oxygen. While often perceived as purely endothermic, the pyrolysis of large wood particles introduces a complex thermal profile due to localized exothermic reactions , particularly at intermediate temperatures. These exothermic effects have significant implications for reactor design, heat transfer modeling, safety, and the quality of biochar and volatiles produced. In large particles, the heat generated from the exothermic breakdown of lignin and hemicellulose can cause internal temperature spikes. These self-heating zones accelerate decomposition, leading to non-uniform pyrolysis , which differs significantly from the behavior observed in finely ground biomass. This internal exothermicity poses both challenges and opportunities. On one hand, it can cause th...
