Zeolites (microporous crystalline materials) are used in industry as molecular sieves which are able to separate mixtures of different hydrocarbons. Monte Carlo simulations of hydrocarbon mixtures within the porous network of the zeolite are presented and the temperature dependence of the separation is analysed. An explanation for the low and high temperature separation is offered based upon the shape of the hydrocarbons and the pore topology. It is also possible to simulate the behaviour of molecules in pores whose diameter is an order of magnitude larger than those of zeolites. A brief introduction to such materials is given, alongwith a discussion of the structure of adsorbed molecules within the pores.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
