One of the challenges that could be overcome with more advanced microstructured designs is the lack of contact between the reactants and the catalytic phase, using geometries that increase the tortuosity of the reagent flow. In addition, the dimensions of the devices and their densities of void fraction and occupied fraction can be controlled, to also manage heat transfer during the catalytic reactions.
In this sense, the present work shows different examples of ceramic and polymeric microreactors (Figure 1) printed by means of stereolithography (SLA), and designed from periodic open cell structures (POCS). These devices have been used as catalytic supports in reactions such as CO oxidation, CO2 methanation and methanol carbonylation. These examples show the advantages of this type of device compared the powder catalysts and point out the strong influence of the microreactor design over the performance.
