Résumé : This paper deals with the possibilities of obtaining biomass coal carbonization method. Different agricultural residues (millet stalks, peanut shells, cashew shells, etc.) from the Casamance region have subjected to a heat treatment in a cylindrical metallic enclosure called carbonizer " 01 fût "). The carbonization yields of these three residues were evaluated and equal to 34.00 %, 34.07 % and 20.99 % respectively for peanut shells, millet stalks and cashew shells. Unburned fractions are respectively of the order of 0.5 %, 0.37 % and 8.95 %. Carbonization of cashew shell remains the slowest, the most difficult and was accompanied by release of the cashew nut shell liquid (CNSL).
