摘要
The objective of this study was to evaluate the effect of radial position and final carbonization temperature on the chemical, physical and mechanical properties of charcoal from wood of Corymbia and Eucalyptus. Three individuals of Corymbia citriodora and two natural hybrids of Eucalyptus urophylla (VM04 and MN463) were cut. One short piece was removed from each individual and it was mechanically processed, so that the samples were removed at three different radial positions for the determination of basic density and for carbonization at three different final temperatures. Charcoal from C. citriodora had higher apparent relative density; mineral content; penetration resistance of the semi-sphere of steel and maximun tension supported. There is a direct relationship between final carbonization temperature and the contents of fixed carbon, resistance and charcoal stiffness. There was an increasing trend in apparent relative density, penetration resistance of the semi-sphere and charcoal maximun tension supported from the pith to the cambium. There was still a tendency towards a higher mineral content for the charcoal produced with the wood closest to the pith.
