Abstract
The world's energy demand is constantly increasing, with almost 85% of energy demand being supplied by the combustion of fossil fuels such as coal, oil and natural gas. The constant use of these fossil fuels has led to the emission of large quantities of greenhouse gases (GHG) to the atmosphere. Biomass is the fourth energy source in the world, its use through the combustion process for power generation presents several challenges due to its irregular geometry, high moisture content and volatile material, low calorific power and high alkaline composition, in addition, their availability and the problems of operation (transportation and storage). In this sense, torrefaction appears as a biomass pretreatment technology. Torrefaction causes a significant increase in calorific power, expressive reduction of moisture content and increase of the apparent density. Among the biomass that has potential for energy generation are agroindustrial and forest residues. Brazil residues derived from the production of eucalyptus have potential for energy generation. Despite the work involving the use of residues derived from eucalyptus production, there are scarce studies on torrefaction of eucalyptus sp. sawdust. The preliminary results show an increase of energy yield of torrefied eucalyptus sp. sawdust. A reduction of particle size has not significant effect on energy yield increase.
