heal.abstract
This dissertation presented below considers the field of printed catalysts as the main subject of its study. 3D printing is an innovative and unique additive manufacturing technology that without doubt offers a high degree of freedom for the creation of various products. Concerning the chemical engineering sector and catalysis in combination with 3D printing is at a very early stage. The ease of access in low-cost, dependable, efficient and unique catalytic materials will be undoubtedly vital in fabrication of monolith catalysts.
Up to this point, there are not many researches in 3D printed catalysts that can be used in catalytic reactions. In view of this, the ultimate goal of this dissertation is the fabrication, testing and characterization of an inexpensive zeolite-based thermoplastic catalytic material that has been prepared into filament form for direct 3D printing. Results from the dynamic ultra-micro-hardness test as well as analysis with microscope are thoroughly presented in order to fully define the structure along with the mechanical properties of the developed composites. The dynamic test leads to good results, as it thoroughly presented below. This dissertation provides starting points for discussion and further research in the
direct printing of functional catalytic materials.
