Resumo: | This research aimed to analyze the quality and yields of the charcoal of a Eucalyptus grandis x Eucalyptus urophylla hybrid clone commercially named GG100 for use in iron industry at different ages, plantation sites and spacing. The wood was carbonized in a laboratorial electric furnace (muffle furnace) at a heating rate of 1.67 ºC min-1 until the final temperature of 450 ºC, remaining stabilized for 30 min. The gravimetric yield in charcoal, pyroligneous extract, non condensable gases and insoluble tar, proximate and elemental chemical composition, relative apparent density and higher heating value of the charcoal were determined. In general, the charcoal evaluated may be considered homogeneous based on chemical and physical aspects and can be used in the steel sector. The apparent relative density allowed the charcoal samples differentiation produced by the same pyrolysis condition. The results obtained suggest that the density of the charcoal is highly influenced by the wood origin. It was observed that higher values of higher heating values are positively related with carbon content and negatively related with oxygen, hydrogen and nitrogen contents and with gravimetric yield in charcoal.
