espanolLa madera de pino representa el 20% de las especies forestales plantadas en todo el mundo, y actualmente es de vital importancia en aplicaciones industriales como en aserrio, fabricacion de papel y medicina. Actualmente, se ha destacado su uso en aplicaciones energeticas. En este estudio se presenta una breve revision sobre el analisis termico realizado a diversas especies de madera de pino. Nos enfocamos principalmente al analisis de los resultados respecto a como varia el contenido de masa o perdida de peso con el cambio de temperatura a partir del analisis de las curvas de termogravimetria y su derivada. Se han considerado diversas especies de madera de pino: Pinus caribaea, Pinus patula, Cupressus sempervirens, Pinus pinaster, Pinus radiata, Pinus sylvestris, Pinus pinea y Pinus taeda. Con el objetivo de mostrar las diferencias y similitudes respecto a la estabilidad termica de las especies mencionadas, se han discutido los principales parametros a partir de las curvas de termogravimetria como energia de activacion, factor pre-exponencial y orden de reaccion. Ademas, se examinan las etapas de descomposicion de acuerdo a los principales componentes de la madera tales como agua, celulosa, hemicelulosa, lignina y extractivos. Palabras clave: Conversion termica, Cupressus sempervirens, energia renovable, parametros cineticos, Pinus sp. EnglishPine 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. Keywords:Cupressus sempervirens, kinetic parameters, Pinus sp, renewable energy, thermal conversion.
