摘要

Elm branches, as a promising but under-exploited biomass resource, was systematically investigated to explore its pyrolysis behavior. The study employed TG-FTIR analysis combined with shuffling complex evolution (SCE) optimization to decouple the contributions of hemicellulose, cellulose and lignin during pyrolysis. The main findings revealed the activation energies for these three components: 86.71, 127.45, and 84.72 kJ/mol as optimized by SCE. Thermodynamic analyses demonstrated low energy barriers and equilibrium-driven reactions. FTIR spectroscopy data identified CO2 as the dominant gas, followed by aldehydes/acids/ketones, CH4 and aromatic compounds. These results highlighted the efficiency of SCE in resolving overlapping pyrolysis process and further established the pyrolysis characteristics of elm branches.
