Activated carbon material has been used for many years in air cleaning applications. Powder form activated carbon has been gradually replaced by activate carbon fibre. which allows much smaller pores - specific area of such material may reach up to 2000 m(2)/g. An experimental dynamic volatile organic compound (VOC) generation system has been developed in order to test new types of activated carbon fibre material. Adsorption capacity measured on VOC (ethyl acetate. xylene & perchlorethylene) of these new products appears high - depending on VOC concentration and number of layers, adsorption capacity many reach 50% in mass at 10% breakthrough. These interesting characteristics coupled with easy handling and lower prices make activated carbon fibre materials attractive for gas cleaning applications.
