The thermal behavior of eucalyptus wood biomass was
examined by TGA (figure not shown). The pyrolysis of eucalyptus
wood, like that of any other biomass comprised mainly of
hemicelluloses, cellulose, and lignin, is associated with the
pyrolysis of these polymers [37]. The TGA curve indicates three
mass loss steps; the evaporation of adsorbed moisture up to 110 8C,
the decomposition of hemicelluloses in the biomass at 250–340 8C,
and the cellulose decomposition at about 380–520 8C [20].
