3D‐printed fluid‐guiding elements for flow control in a microstructured membrane reactor for H<sub>2</sub>O<sub>2</sub> direct synthesis

A microstructured membrane reactor has been developed to overcome the safety and productivity challenge of the direct synthesis of hydrogen peroxide. A single membrane is employed for separate, continuous dosage of the gaseous reactants hydrogen and oxygen to the solid catalyst present in the aqueous solvent. Using a custom OpenFOAM® model, the impact of catalyst‐coated static mixers with different mixer geometries is studied. It is demonstrated that the custom fluid guiding elements outperform the investigated commercial static mixer under the flow conditions relevant to this application.

“…They can offer superior process performance due to greatly increased control over heat and mass transfer inside the apparatus and lower pressure drop. These 3D-printed structured catalysts include the POCS (periodic open cell structures) system pioneered at Erlangen [6][7][8], DPSRs (designed porous structured reactors) pioneered at Zurich [9,10], catalytic FGEs (fluid guiding elements) pioneered at KIT [11,12] and CSMs (catalytic static mixers) pioneered in our group at CSIRO [13][14][15]. Our team has evaluated CSMs for the use in industrial type hydrogenations in specifically designed tubular and microstructured flow reactors.…”

Structured catalysts made by additive manufacturing offer the capability to seamlessly scale heterogeneous catalysis from lab to production with minimal effort to reengineer the process at intermediate steps. They can be tailored to meet certain process demands for mixing, heat transfer and flow resistance, in order to overcome flow maldistribution, hotspot or pressure drop issues, generally associated with traditional packed bed systems. Herein we investigate the long‐term durability of 3D‐printed Pd catalytic static mixers for their use in the hydrogenation of 4‐nitrobenzoic acid.
