| description | This work proposes to use core-shell structured spheres to evaluate whether it allows to individually optimize bulk and surface effects of a packing material, in order to optimize conversion and energy efficiency. Different core-shell materials have been prepared by spray coating, using dense spheres (as core) and powders (as shell) of SiO<sub>2</sub>, Al<sub>2</sub>O<sub>3</sub>, and BaTiO<sub>3</sub>. The materials are investigated for their performance in CO<sub>2</sub> dissociation and compared against a benchmark consisting of a packed-bed reactor with the pure dense spheres, as well as an empty reactor. The results in terms of CO<sub>2</sub> conversion and energy efficiency show various interactions between the core and shell material, depending on their combination. Al<sub>2</sub>O<sub>3</sub> was found as the best core material under the applied conditions here, followed by BaTiO<sub>3</sub> and SiO<sub>2</sub>, in agreement with their behaviour for the pure spheres. Applying a thin shell layer on the cores showed equal performance between the different shell materials. Increasing the layer thickness shifts this behaviour, and strong combination effects were observed depending on the specific material. Therefore, this method of core-shell spheres has the potential to allow tuning of the packing properties more closely to the application by designing an optimal combination of core and shell. |
