AB - The paper studies process of interaction of a moving molecule with structure  atoms. The mathematical description is based on application of Hamiltonian  systems model and numerical methods for solving the basic problem of  molecular dynamics. The interaction between individual atoms and the  simplest molecules is cared out using the classical Lennard-Jones potential.  Polyethylene nanostructures are considered as filtering elements for  selective separation of natural gas mixtures, in particular, their light  components: hydrogen and helium. The influence of geometric dimensions and  geometric features of a nanostructure on selectivity of gas mixtures  separation is studied.
