Abstract

The permeation of CO2/N2-gas mixture through zeolite membranes was investigated by molecular dynamics (MD) study. MD calculation successfully reproduced the experimental results of CO2/N2 separation by NaY membrane. Furthermore, the surface difference effect on gas separation was examined using the NaA zeolite (100) surface and its (111) surface. The CO2/N2 separation factor of the (111) surface was much lower than that of the (100) surface. This was caused by the difference in surface structure, since the pore structures of both models were the same.
