This paper shows the results of the thermal treatment effect on Pinus taeda L. pellets. The torrefaction of the fresh pellets was conducted at 200-300 degrees C for 30-90 min in a completely randomized factorial design followed by multiple linear regression analysis. The evaluation of the gravimetric yield (GY), equilibrium moisture content (U-eq), and high heating value (HHV) as a function of time and temperature of torrefaction indicated that this process decreased the GY and U-eq of the pellets, which resulted in fuels with higher energetic content when compared to the fresh Pinus taeda L. pellets.
