Torrefaction is a thermal treatment that promotes homogenization and improvement of energy properties of biomass. This study aims to evaluate the effects of torrefaction on the main energy properties of Eucalyptus grandis wood. Wood was torrefied at three distinct temperatures (220°C, 250°C and 280°C) and analyzed for gravimetric yield (ratio of dry wood mass to torrefied wood mass), bulk density (ratio of dry torrefied mass to dry torrefied volume), heating value (higher – HHV, lower – LHV and useful – UHV), energy density (ratio of heating value to bulk density) and energy yield (product of gravimetric yield and ratio of HHV of torrefied wood to HHV of feedstock). The obtained results revealed significant differences for all properties being analyzed except for bulk density, which showed no statistical difference between the control and the treatment at 220°C. Temperature 250°C generated the best energy density as a function of the increase in heating value and the slight decrease in bulk density. |
