Adsorption of Super Greenhouse Gases on Microporous Carbons

摘要

Grand canonical Monte Carlo simulations are reported for low molecular weight perfluorocarbons (C_2F_6 and CF_4) and their dilute (10% molar) mixtures in N_2 adsorbing unto slitlike graphite pores.Adsorption isotherms and selectivity plots are shown for various temperatures,pressures,and pore widths.It is shown how selectivities on the order of thousands may be obtained when appropriate pore widths and thermodynamic conditions are used.Selective entrapment of these super greenhouse gases onto carbon nanopores is shown to be a promising alternative in the remediation of air streams.
