To utilize the fast-growing Eucalyptus residue (FGER) for energy application, the pyrolysis kinetics of FGER was studied by a new simple distributed activation energy model (DAEM) through thermogravimetry analysis at different heating rates of 10, 20, 30, 40, and 100 °C/min from room temperature to 1000 °C. The results showed that the DAEM could fit the experimental data well. The pyrolysis weight loss process of FGER could be divided into four stages. The first and second stages were attributed to hemicellulose decomposition located at α= 0-0.1 and α= 0.11-0.34 with activa...
