El objetivo del presente trabajo fue proponer una alternativa más eficiente del uso de residuos de aserraderos para optimizar el rendimiento en peso de carbón y el rendimiento en carbono fijo. Para ello, se procedió a fabricar carbón por destilación seca, de acuerdo a un diseño experimental compuesto controlando los siguientes parámetros: velocidad de calentamiento entre 60 y 120 ºC·h-1 y temperatura final de carbonización entre 450 y 550 ºC. Los resultados arrojan un rendimiento en peso de carbón del 48 % trabajando con una velocidad de calentamiento y temperatura final de carbonización baja, disminuyendo este rendimiento a un 36 %, cuando se trabaja a velocidades de calentamiento y temperaturas finales de carbonización, altas. En lo que respecta a rendimiento en carbono fijo, su comportamiento es de manera inversa en referencia a las variables antes mencionadas, pero siempre con un rendimiento superior al 82 %.]]></p></abstract>

Consequently, the aim of this work was the finding of more efficient alternative of the use of sawmills wastes in order to optimize the weight yield of charcoal and the fixed carbon yield. In the way, charcoal was made by dry distillation, on the basis of a composite experimental design controlling the following parameters: heating speed (between 60 and 120 ºC·h-1) and a final carbonization temperature of range between 450 and 550 ºC. Result showed that a 48 % weight yield, was attained at the lowest laves of heating speed and final carbonization temperature, while working at the highest levels of these parameters gave a lower yield (36 %).Regarding the fixed carbon yield, it had a conversely behaviors towards the above mentioned variables, but it always yielded levels higher than 82 %.]]></p></abstract>
