A two-step agglomeration model is developed for the crystallization of a zeolite. It accounts for the crystallization of crystallites from the amorphous phase and the subsequent growth and agglomeration processes. The model explains the morphology of agglomerates with multiple structures, which were obtained. When porosity of the secondary agglomerates is introduced in the model, the agreement with experimental data is largely improved.
