【 摘 要 】

Pine wood accounts for 20% of the world's planted forest species, and is currently of vital importance in industrial applications such as sawmills, papermaking and medicine. Actually, its use in energy applications has been emphasized. This study presents a brief review on the thermal analysis of various species of pine wood. We focus mainly on the analysis of the results regarding how the mass content or weight loss varies with the temperature change from the analysis of the thermogravimetric curves and its derivative. Several species of pine wood have been considered: Pinus caribaea, Pinus patula, Cupressus sempervirens, Pinus pinaster, Pinus radiata, Pinus sylvestris, Pinus pinea and Pinus taeda. In order to show the differences and similarities with respect to the thermal stability of the mentioned species, we have discussed the main parameters from the thermogravimetry curves such as activation energy, pre-exponential factor and reaction order. In addition, the decomposition stages are examined according to the main components of the wood such as water, cellulose, hemicellulose, lignin and extractives.
