Simulation of Fluid Flow During Direct Synthesis of H₂O₂ in a Microstructured Membrane Reactor

Abstract

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.

Potenzial von Membranen zur verbesserten Reaktionsführung von Selektivoxidationen: Katalysator‐, Reaktor‐ und Prozessebene

“…Vielversprechende neue Ansa ¨tze wurden 2019 auf der 14th International Conference on Catalysis in Membrane Reactors in Eindhoven u. a. von den Arbeitsgruppen Dittmeyer, Gallucci und van Sint Annaland zur Thematik Wasserstoffperoxidsynthese, oxidative Methankopplung und Wasserstoffproduktion vorgestellt [90][91][92].…”
