A molecular dynamics calculation of a realistic model of xenon adsorprion in sodium-Y zeolite is reported. The equilibrium properties such as the energy distribution function, the centre-of-cage-centre-of-mass radial distribution function, and the cageoccupancy distribution function are obtained. Th

β¦ Synopsis
Molecular dynamics calculations have been used to investigate theeffect of temperature on the mobility of methane in faujasite. At room temperature, methane molecules reside mostly in the vicinity of the supercage walls. Migration between supercages of the zeolite structure occurs predominantly via surface diffusion.

## Abstract Molecular Dynamic (MD) simulations were carried out to determine the MaxwellβStefan (MβS) diffusivities, Δ~i~, and selfβdiffusivities, __D__~i,self~, of methane (C1), ethane (C2), and propane (C3) for a variety of molecular loadings, __q__~i~, in three classes of zeolite topologies: (1)
Diffusion coefficients D 1 and D 2 of a binary mixture of adsorbates of diameters 0-1 and 0-2 in the restricted regions of zeolite NaY have been obtained from molecular dynamics simulations. The results suggest that the ratio of the diffusion coefficients ff = D1/D 2 exhibit unusual behaviour with a
