Comparative study of some carbonization process parameters of nine eucalypt woods from hajeblayoun arboretum in Tunisia

The objective of this work is to study the calorific power of nine eucalypt woods from  central  Tunisia  for  carbonization  process.  The  ignition  temperature,  the calorific  power  of  each  species  and  the  gas  exhaustion  during  pyrolysis  were measured  and  their  average  values  were  compared.  The  calorific  values  of  the wood  of  these  species  varied  between  4017  and  4541  Kcal/kg.  The  ignition temperature ranged between 252 and 390°C. The combustion temperature of the samples within the calorimeter was between 463 °C and 575°C. The percentage of  wood  ash  after  combustion  was  between  1.0  to  2.2  %.  The  analysis  of  the  experiments  conducted  during  2  consecutive  years  showed  that  certain  species were similar while others were significantly different.
