摘要：

The diffusion of methane in silicalite at high dilution was studied by molecular dynamics both using a vibrating framework model, and keeping the framework fixed. Methane molecules were represented by Lennard-Jones particles. The diffusion coefficients resulted in agreement with experiment. The effect of the vibrating framework on the diffusive process is discussed and a detailed analysis of the behaviour of methane molecules in silicalite is reported.
