This research focused on developing granulation technology for metal-organic frameworks (MOFs). The granulation process was optimized by exploring the granulation mechanism of fresh and recycled MOF powders in the high shear granulator. Experimental results indicated that the plastic limit of MOF powder determined the adhesive content at which the agglomerate begins to behave as a plastic material, that altered the size distribution of MOF granules in the granulation process. The equilibrium of coalescence and agglomerate breakage phenomena for the fresh MOF resulted in a stable normal distribution of granule size in the high shear granulator. The consolidation and coalescence were the dominate mechanisms for recycled MOF granulation, accelerating granule growth into large granules or agglomerates. The optimized MOF granulation process yielded 85% MOF granules (2~5 mm), which can serve as reference for developing a commercial MOF granulation process.
