ABSTRACT
Eucalyptus urophylla wood and three residues of the mechanical processing of Eucalyptus spp wood (chips, peels and shaving wood) were carbonized under maximum temperatures of 400 oC and 600 oC. The yield in charcoal and carbon, besides the content of condensed gases, non-condensed gases, volatile materials, ash and fixed carbon were estimated. The chips, when submitted to the pyrolysis in the maximum temperature of 600 oC, resulted in the best energetic properties, in comparison to the other residues of the mechanical processing of the eucalypt wood (Eucalyptus spp) and Eucalyptus urophylla log.
