Abstract (en)

[origin: FR2760759A1] The invention concerns a carbon precursor cellulose fibre texture impregnated with a composition containing at least a mineral constituent with a function promoting cellulose dehydration, and subjected to thermal treatment, consisting in a rise in temperature at a rate ranging between 1 and 15 DEG C/minute followed by a stage at a temperature between 350 and 500 DEG C, and followed by a step of washing the texture. An activated carbon fibre texture is directly obtained with a specific surface area not less than 600 m<2>/g, without subsequent activating treatment at higher temperature.
