We have tried wood carbonization of eigth species from forest and fruit-trees found in Tunisia. The wood humidity of the different types has varied from 16 to 20% and the density is in the order of 0,8 to 1,1%. The duration of carbonization was from 110 to 130 hours. The temperatures of combustion were between 600 and 700 degrees C during the carbonization. The technical efficiency of the carbonization from species wood was between 6 and 25%. The best yield obtained of different species studied were of olea europea and citus aurantium.
