In the present paper, the Independent Parallel Reaction Model (IPR Model) is applied to describe the slow dynamic pyrolysis of sugar cane bagasse, witch is studied by thermogravimetric analysis of three ranges of particles diameter. The kinetic parameters and mass fraction of each principal pseudo-component of biomass (hemicellulose, cellulose and lignin) are estimated using the Differential Evolution Algorithm. Good fits to weight loss curve were obtained at different heating rates. The mass fractions and Arrhenius parameters estimated are compared with the experimental values reported by literature with good agreement.
