ResumenCO2 adsorbents of high capacity were prepared from biomass residues. Two different methods for producing these adsorbents were compared: activation with carbon dioxide and heat treatment with ammonia gas (amination). The prepared carbons were physically and chemically characterised. Amination at 800 ºC introduced nitrogen into the carbon structure, turning the carbon surface more basic. On the other hand, activation with carbon dioxide led to a significantly higher texture development. The prepared adsorbents presented high CO2 capture capacities and showed fully reversible adsorption. Amination led to higher CO2 capture capacities in a volumetric basis. Thus, amination appears to be an appealing process for obtaining CO2 adsorbents.
