POTENTIAL OF CHARCOAL FROM NON-COMMERCIAL Corymbia AND Eucalyptus WOOD FOR USE IN THE STEEL INDUSTRY

The present data are from the evaluation of quality and combustion behavior of new and non-commercial charcoal species in Brazil, which can potentially be used in the steel industry. Seven six-year-old trees from eight species, namely, Corymbia citriodora, C. variegata, C. henryi, C. torelliana, Eucalyptus amplifolia, E. longirostrata, E. major, and E. urophylla were sampled and carbonized on a laboratory scale. The gravimetric yields of the carbonization process, proximate and ultimate chemical analysis of charcoal, apparent relative density (ARD) and energy density (ED), higher heating value (HHV), ignition (Di), and combustion (Si) indexes through the curve of thermogravimetric derivative (DTG) were determined.
