Resumen
Descripción
The study presented in this paper is an investigation on the porosity changes induced by thecarbonization of Tunisian olive wood. The porosity is measured by mercury porosimetry. Theexperimental results show that the total porosity of carbonized wood increases with the temperature. Itshould be underlined that the formation of some macropores during the increase of the temperature iscertainly due to the breaking of the cell wall by the mercury penetration. The weakness of the cell wallis observed when the degradation rate of the three pseudo components of wood, the notion of whichhas been introduced by the authors in a previous article [Grioui et al. 2006], becomes high whichcorresponds to the temperature range between 523 K and 548 K.
