本研究針對金屬有機骨架（MOF）造粒成型技術進行開發，探討MOF於快速混合造粒過程粒子間聚合現象，釐清MOF新料粉體及回收破碎再使用之回料粉體之差異性，並進行MOF造粒製程參數優化。研究結果發現：新料及回料粉體最密堆積時之孔隙率差異，會影響呈現塑性所需要的最低黏著劑含量，進而影響後續造粒製程的結果。MOF新料於造粒過程中，其顆粒會歷經併聚及破碎機制，最終達到穩定的粒徑分布；MOF回料於造粒則無顯著破碎機制，導致顆粒加速成長變為大粒徑顆粒或團塊。經探討影響因子與參數優化後，MOF造粒製程產率達85%，可作為未來MOF商業化發展之參考依據。

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.
