Abstract: Detailed kinetic triplets and thermodynamic studies of the three main components are important in the efficient design of the pyrolysis process. In this work, the three main components (cellulose, hemicellulose and lignin) of lignocellulosic biomass were extracted from bamboo residues (BR). The kinetic triplets and thermodynamic parameters of BR and its three components were then interpreted using thermogravimetric analysis. Three iso-conversional methods (Friedman, Flynn-Wall-Ozawa and Kissinger-Akahira-Sunose models) estimated the average activation energy of BR and the extracted cellulose, hemicellulose and lignin to be 164.5, 145.3, 186.0 and 182.7 kJ mol−1, respectively. The frequency factors of BR ranged from 1013 to 1018 min−1 according to the Kissinger method, and the average frequency factors of the three main components were cellulose < hemicellulose < lignin. The master plots reveal the dominance of the diffusion mechanism in the pyrolysis process. The change in enthalpy (109.5–297.1 kJ mol−1) and Gibb free energy (138.7–156.3 kJ mol−1) indicated the endothermic and non-spontaneous nature of the pyrolysis of BR and the three main components. Kinetic and thermodynamic analyses confirmed the feasibility of BR as a potential candidate for bioenergy.
