Separation of CO2/CH4 were investigated using (SAPO-34) CHA and Deca-dodecasil3R (DDR) at 300K. in the context
of zeolites membrane separation of CO2/CH4 mixtures ,CHA and DDR are better than MFI. It was found that applying
two layer of zeolite in order first CHA and then DDR can improve the selectivity and enhanced the flux if we use them
at feed and permeate side of the support. A sufficient model, based on the generalized Maxwell-Stefan equations, has
been used to describe the transport mechanism in the membrane. The diffusivity of these species is strongly dependent
on the loading that has been described by Reed and Ehrlich [1] model. Also we used molecular dynamic results [2].
