Abstract

The aim of this study was to evaluate the steel and energetic potential of charcoal of clones of Eucalyptus grandis and Eucalyptus urophylla at 42 months of age. Wood from seven clones were used. The carbonizations were performed in an electric furnace (muffle) with final temperature of 450 °C. The carbonization yields, immediate and elemental chemical composition, higher and low heating value, apparent relative and energetic density and fixed carbon stock were determined. For data analysis, the principal components analysis was used. The clones G129 and U059 stood out for steel and energetic use, fixed carbon stock, yields in charcoal, fixed carbon and in pyroligneous liquid, and for the lower values in non-condensable gases. These clones were considered as one group by the multivariate statistical analysis. In general, low influence of clone effect in the immediate chemical composition and higher and low heating value of the charcoal was noted. This result was attributed to the use of the same temperature of carbonization for all clones and the age of assessment.
