Abstract

The aim of this work was the kinetic analysis of the thermal decomposition of four Brazilian lignocellulosic biomasses: caixeta wood (Tabebuia cassinoides Lam.), rice husk (Oryza sativa L.), sugarcane bagasse and straw (Saccharum officinarum L.). The thermal decomposition experiments were carried out in a thermogravimetric analyzer using a heating rate of 10 °C/min. The kinetic analysis of the biomass thermal decomposition was carried out applying a scheme of three independent parallel reactions. The results showed that the model was in agreement with the experimental data, and the activation energies obtained were between 118-130 kJ/kmol, 200-215 kJ/kmol, and 100-150 kJ/kmol, for hemicelulose, cellulose and lignin modeled reactions, respectively. Also, were determined linear correlations between the logarithm of the pre-exponential factor and activation energy for each reaction evaluated, and tested in the biomasses analyzed. Finally, was concluded that the correlations obtained could be used for the determination of the kinetic parameters of the thermal decomposition of several biomasses, contributing to the modeling process by reducing the time invested in the iteration process.
