Abstract: The CF-PAN activation process with CO2 has been analysed. Activation of CF-PAN with CO2 leads to unusual results both, activation percentage evolution over the time and generated porosity development. In the explanation has been highlighted the role of the carbonization step in the CF-PAN activation process. The analysed results point to the fact that part of the released nitrogen-containing compounds during PANOX fibres carbonization are deposited on the CF surface, which affects to carbonized PAN fibres, decreasing actives sites, or acting as inhibitors of the gasification reaction.
