Abstract The use of biomass to produce energy is becoming more and more frequent as it helps to achieve a sustainable environmental scenario. However the exploitation of this fuel source does have drawbacks that need to be solved. In this work, the torrefaction of woody biomass (eucalyptus) was studied in order to improve its properties for pulverised systems. The process consisted in a heating treatment at moderate temperature (240, 260, 280 °C) under an inert atmosphere. The grindability of raw biomass and the treated samples was compared and an improvement in the grindability characteristics was observed after the torrefaction process. Thermogravimetric analysis of the samples was carried out in order to study their reactivity in air. The DTG curves of the torrefied biomass showed a double peak nature. The kinetic parameters were calculated for each reaction stage. The torrefaction process was found to influence the parameters of the first stage, whereas those corresponding to the second remained unaffected.

Effect of Torrefaction Process Parameters on Biomass Feedstock Upgrading (2010, methodology): “In addition, storing such enormous amounts of wet biomass will further increase expenses through high rate of dry matter loss due to microbial activity and hazard of self-heating/combustion (Biomass Research Committee, 2007; Bridgeman et al., 2008; Arias et al., 2008, Lipinsky et al. 2002).”
