Gas sorption studies on Zeolite Y membrane materials for post-combustion CO2 capture in coal-fired plants

- CO2, N2 adsorption energies; monolayer adsorption constants on Zeolite NaY.
- Sorption, desorption and exchange kinetics for CO2 and H2O.
- CO2 sorption times on the order of 10 min for CO2 and hours for H2O.
- Estimated permeances in bulk Z-NaY insufficient to explain membrane performance.
- Adverse effect of H2O on CO2 transport in coal plant post-combustion flue gas.
