Zeolite membranes have shown promising applications in catalytic and separation processes in chemical industry. A simulation-assisted design method based on experiments and simulations is shown to guide the development of hierarchically structured catalyst systems based on zeolite membranes by predicting the optimal catalyst structure. A cornerstone of this method is a 3-D pore network model – crystallite-pore network model for simulation of diffusion and reaction in polycrystalline zeolites.
