|Description: ||In the present studied was investigated hybrids of Eucalyptus grandis x Eucalyptus urophylla in three different ages. Wood and charcoal characteristics as well as the influence of wood characteristics on the charcoals produced were evaluated. Chemical analyzes (extractives, lignin, ash, elemental analysis), basic density and calorific value - PCS were performed for wood. The charcoals were produced in a muffle type furnace with a heating rate of 1.67 °C.min-1 and an end temperature of 450 °C. Volatile material content, ash content, fixed carbon content, elemental analysis and gravimetric yield of the pyrolysis process were performed for the charcoals. An increase in density values, extractives content, carbon content and C/H rate were observed with the maturity of the tree. Other features such as ash content and S/G ratio decreased with the age of the tree. Greater gravimetric yield in charcoal and non-condensable gases were found in more mature materials.|
