- Abstract: Given the interest of using biomass as a renewable source for generation of energy, wood is a strong candidate because it is considered a neutral emission biomass. Eucalyptus spp. has a high productivity when coming from a traditional forest (20tDB/ha.year) and a short rotation energy forest (40tDB/ha.year). The objective of this work was to evaluate the influence particle size of Eucalyptus spp. Vale do Paraíba region in the torrefaction process - a thermochemical process that has been used as a heat pretreatment method that improves many of the limitations of in natura wood. The experiment was conducted with three particle sizes: the first being the chip as it comes out of the industrial chipper with size between 18 and 6mm and the other two sizes, the chip mill ground with 9 and 4mm sieve knives with particles between 4 and 0.4mm and 1.4 and 0.25mm, respectively. The samples were submitted to the torrefaction process at 260°C for 30minutes to evaluate the changes in the torrefied biomass. The results showed that there was loss of mass, and the torrefied biomass was 81.6%, 79.1% and 73.9% according to particle size reduction, while the fixed carbon and higher heating value had no significant changes as a function of particle size under study. After the torrefaction process, the fixed carbon increased by 1.38 times and the higher heating value increased by 1.14times compared to the raw biomass. Considering that wood chips rarely come in the same size, and studies have shown that there were no significant changes on the biomass after torrefaction, it is possible to use as raw material the wood chips that comes from the industrial chipping process, and to grind the torrified biomass form during the milling process leading to energy savings for the purpose of particle reduction to smaller sizes.
