| contents | Experimental study of thermal effect on olive wood porous structure during carbonization Najla Grioui Kamel Halouani André Zoulalian Foued Halouani Agrociencias olive wood carbonization porous structure mercury porosimetry 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. 2007 artículo científico 0717-3644 https://www.redalyc.org/articulo.oa?id=48590102 en http://www.redalyc.org/revista.oa?id=485 Maderas.
