Abstract:
The Coats-Redfern method was used to analyze the kinetic characteristics of biomass catalytic pyrolysis, indicating that it can be described by multi-step reactions, rather than as a simple first-order reaction. Friedman model-free calculations were used to describe the starting reaction types and the corresponding initial kinetic parameters. Finally, nonlinear regression of biomass catalytic pyrolysis showed that the reaction mechanism of the whole process could be kinetically characterized by three successive reactions: a one-dimensional diffusion reaction, followed by an apparent first-order reaction, and then by a two-dimensional diffusion reaction. The kinetic parameters and equations were also calculated.
