The 'shape selectivity' of zeolites can be rationalized using a straightforward thermodynamic analysis of how pore topology affects the free energies of formation of the reactants, intermediates and products involved in the chemical transformations for oil refining catalysed by the zeolite. It is shown that despite some drastic simplifications, the approach can even guide the search for zeolite structures that are particularly suitable for desired catalytic applications.
