Resumo: The objective of this study was to determine the influence of the chemical properties (elemental composition, levels of extractives, lignin total and holocellulose) and the syringyl/guaiacyl, wood of different Eucalyptus genetic materials in the production of charcoal. It was used in the study four hybrid clones, at age of 7 years, 6 trees per clone, totaling 24 sampling units. There was significant difference, at 5% significance, between treatments for elemental composition, levels of extractives, lignin total and holocellulose and the wood syringyl/guaiacyl, as well as for gravimetric yields in charcoal, condensable gases and non-condensable gases, levels of fixed carbon and volatiles, and for the higher calorific value of charcoal. For the ash content and relative apparent density of charcoal were not observed significant differences at the same level of significance. Concluded that there is variability in the wood quality of four evaluated genetic materials, having the same, distinct correlations, thus the yield and the quality of charcoal. All genetic material presented satisfactorily gravimetric yield in charcoal and quality. The woods of clones with low syringyl/guaiacyl ratio showed an increase in yield in charcoal. The chemical composition of woods from the four clones, in general, showed no significant correlations, the 5% significance level, at the yield and quality of charcoal.
