Resumen
[es] El presente Trabajo de fin de Grado explora la fabricación de monolitos cerámicos con estructuras regulares de porosidad abierta que se generan a partir de la proyección de una celda unitaria y en este caso aplican celdas unitarias que se observan en la naturaleza, destacando una aproximación de celda escutoide, una geometría observada en la configuración de las células de tejidos epiteliales. El objetivo de replicar estas estructuras en un sistema cerámico es el de trasladar posibles ventajas del diseño avanzado al desempeño del bloque estructurado cuando se utiliza como soporte de un catalizador en una reacción catalizada. Por lo tanto, se estudia el desempeño de las estructuras en la reacción de reformado seco de metano. De manera complementaria, se aplican herramientas computacionales haciendo análisis de ciclo de vida para analizar el impacto ambiental del mismo, comparándolo con la fabricación de bloques monolíticos obtenidos mediante técnicas de fabricación tradicionales.
[en] This Final Degree Project explores the manufacture of ceramic monoliths with periodic open cell structures. Said structures are generated from the projection of a unitary cell and in this case, unitary cells that are observed in nature haven been applied, especially highlighting an approach of scutoid unit cell, a geometry that is observed in the configuration of epithelial tissue cells. The goal of replicating these structures in a ceramic sistem is to translate potential advantages of advanced design into the perfomance of the structured blocks when used as a catalyst supports in a catalyzed reaction. Therefore, the perfomance of the structures coated with a Rh/Al2O3 was studied in the dry reforming of methane. Moreover, given the novelty of this manufacturing method, computational tools are applied to analyze its environmental by means of life cycle analyses, comparing it with the manufacture of monolithic blocks obtained through traditional manufacturing techniques.
