Abstract: The objective of the study was to verify the influence of plant spacing on a hybrid of Eucalyptus grandis x Eucalyptus camaldulensis on the gravimetric yield and charcoal properties. The determination of the chemical composition, density and the calorific value of the charcoal were carried out. Values of dry mass, carbon mass, lignin content, charcoal yield and available energy as a function of spacing were also analyzed. Five spacings were evaluated: 3.0 x 0.5; 3.0 x 1.0; 3.0 x 1.5; 3.0 x 2.0 and 3.0 x 3.0 meters, and from each plant spacing were selected three trees, characterizing three replicates. Discs were removed from the trees at 0%, 25%, 50%, 75% and 100% of the commercial height of the trunk. For each tree analyzed, the carbonization was performed from a composite sample obtained by samples of the discs. The results show that for dry mass, carbon mass, lignin mass, energy mass stored per hectare / year, gravimetric yield and charcoal properties, the best spacing was 3.0 x 1.5 meters, in order to plant trees for the production of charcoal.
