摘要：

Experiments of H2O and N-2 adsorption in silicon carbide-derived carbon (SiC-CDC) are reported, showing only weak adsorption of N-2, with H2O adsorption being highly kinetically restricted due to the strong hydrophobicity of this material. Such results suggest that SiC CDC is an attractive option for adsorptive CO2, as our prior experiments have shown much more significant adsorption of this gas. This is confirmed by grand canonical Monte Carlo simulations, which show that in a 2-stage adsorption system the CO2 mole fraction can be increased from 15% (typical of flue gas) to 80-99.6% for the pore sizes that comprise the SiC-CDC.
