Comparative Study of Some Carbonization Process Parameters of Nine Eucalypt Woods from Hajeblayoun Arboretum in Tunisia

摘要

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.
