- ENERGY PROPERTIES OF WOOD PARTICLES TORREFIED AT DIFFERENT TEMPERATURES Carlos Miguel Simões da Silva Benedito Rocha Vital Angélica de Cassia Oliveira Carneiro Aylson Costa Oliveira Solange Oliveira Araújo Mateus Alves de Magalhães Agrociencias Torrefaction Energy Properties Higher Heating Value The objective of this study was to evaluate the effect of the final torrefaction temperature on the energy properties of wood. It was applied four treatments with three replicates, consisting of untreated wood particles and particles torrefied at temperatures of 170, 220 and 260°C. Better physical, chemical and thermal properties of the particles were observed as a function of the torrefaction temperature. Comparing with the control group, the particles torrefied at the highest final temperature (260°C) showed significant differences in bulk density - from 239 to 396kg/m³; the equilibrium moisture content changed from 12.3 to 5.7%; fixed carbon content - from 13.0 to 24.8%; heating value - from 4,465 to 4,945kcal/kg; and energy density - from 882 to 1,727Mcal/m³. It was concluded that torrefaction had a positive effect on the energy properties of the wood. 2017 artículo científico 0100-6762 https://www.redalyc.org/articulo.oa?id=48853328004 en http://www.redalyc.org/revista.oa?id=488 Revista Árvore application/pdf Universidade Federal de Viçosa Revista Árvore (Brasil) Num.4 Vol.41
