高升温速率下纤维素热解动力学研究
The pyrolysis behavior of cellulose was researched at multiple heating rates (100,200,400,600,800 K/min) by thermogravimetric analysis.The kinetic parameters were determined by a first order reaction model. Apparent activation energies for cellulose pyrolysis were 146-69 kj/mol, log A were 12.1-6.2 min-1 at the heating rates of 100-800 K/min. The simulated DTG curves calculated by the determined kinetic parameters have a well agreement with experimental data. Activation energies and pre-exponential factors for cellulose pyrolysis are related to heating rate and they can be predicted by the simulation and extrapolation.
