Abstract

Continuum and stochastic mathematical models are introduced describing zeolite nucleation and crystal growth from precursor gels. Model predictions are in agreement with existing experimental results. For example, the maximum in the nucleation rate profile under constant supersaturation is observed well before substantial crystallization occurs. Moreover, simulations indicate a strong influence of the gel microstructure on apparent crystallization kinetics, as well as particle size and morphology.
