The Distributed Activation Energy Model (DAEM) was used to determine the pyrolysis kinetics of wood pellets. The Miura and Maki three­curve method was applied, using heating rates of 10, 15 and 20 K/min to obtain the activation energy, Ea, and the frequency factor, k0. The devolatilization curves were predicted for heating rates up to 200 K/min and compared with independent experimental data obtained with a thermogravimetric analyzer.
