Volatile Organic Compounds represent a large panel of molecules emitted both by human activities and natural production. In order to treat this kind of organic pollution, adsorption with activated carbon is commonly used. This epuration process is quite efficient and present low-cost. However, high flammability, low lifetime and insufficient mechanical firmness, often combined with its limited regenerability, make to explore new ways for the elaboration of industrial adsorbents. Two ways for the elaboration of new adsorbents are developed based on pyrolysis procedures and Chemical Vapour Deposition (CVD) : the non-catalytic heterogeneous pyrolysis of olefinic precursor on alumina or zeolite and the catalytic pyrolysis of acetylene on Fe, Ni, Co catalyst supported by alumina leading to the synthesis of carbon nanofibers. The adsorption capacities sudies show the efficiency of these new hydrophobic adsorbents for gas treatment or gas analysis.
