| 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... |
