Abstract
Low cost carbons obtained from biomass residues, olive stones and almond shells, were evaluated as CO2 adsorbents in postcombustion conditions (low CO2 partial pressure). These carbons were prepared from biomass chars by means of two different methods: physical activation with CO2 and amination. All the prepared carbons present a high CO2 adsorption capacity at 303 K, although carbons developed from almond shells show a superior CO2/N2 selectivity (lower N2 adsorption) than those obtained from olive stones. In general, activated samples present faster adsorption kinetics due to the presence of transport pores, although they have lower densities. On the other han...
