Design of 3D-printed structures for improved mass transfer and pressure drop in packed-bed reactors

Continuous stirred tank reactors in fine chemical synthesis for efficient mixing, solids-handling, and rapid scale-up

“…The widely used methods to be cautious are conductivity and light absorption, often having a limited dynamic range. We use fluorescence for its simplicity, linearity, and wide range [13]. Such measurement systems, however, suffer from non-linearity at high concentrations and may be prone to artefacts requiring careful system calibration.…”

Low Tortuosity 3D‐Printed Structures Enhance Reaction Kinetics in Electrochemical Energy Storage and Electrocatalysis

“…Chatre et al designed a reactor composed of a well‐defined pillared structure using SLA printing and random packing methods ( Figure a). [ 56 ] Printed structures are less than 4% of the reactor volume. The pillared structure enabled structure‐directing filler and more uniform porosity.…”

3D-Printed Cyclodextrin Polymer Encapsulated Wells–Dawson: A Novel Catalyst for Knoevenagel Condensation Reactions

“…In this context, numerous catalysts and electro- and photocatalysts have been previously documented. As an illustrative instance, Chatre et al devised a simplified methodology for structure-directed random packing, aimed at enhancing gas–liquid interfacial area and mitigating pressure drop. This approach involved the utilization of 3D-printed structures enveloped by randomly packed spherical particles.…”
