摘要
The pyrolysis kinetics is very important for the development of biomass thermal chemical conversion technology.By means of the TG-DTG analysis,the pyrolysis behavior and kinetics of corn stalk were investigated with the heating rate from 5℃/min to 100℃/min.The experimental data reveal that the kinetic parameters are much influenced by the operating conditions.And the activation energy of pyrolysis reaction increases with heating rates.Through the kinetics compensation processing,the apparent kinetic parameters of pyrolysis are obtained with the activation energy of 66.5kJ/mol and the frequency factor of 3165s-1.A kinetic model is validated for the corn stalk pyrolysis,which can well fit the experimental results.Moreover,some fundamental data of pyrolysis is provided,which is much valuable for the understanding of process mechanism.
