3D-Printed Fe/γ-Al2O3 Monoliths from MOF-Based Boehmite Inks for the Catalytic Hydroxylation of Phenol

Alma D. Salazar-Aguilar et al.

Summary: The 3D printing of Fe/gamma-Al2O3 monoliths with Fe-MOF-based inks allows for the production of catalytic structures with highly dispersed Fe clusters, nanoclusters, and nanoparticles. By conducting the phenol hydroxylation reaction in a flow reactor using these printed scaffolds, a DHBZ selectivity of 100% and a yield of 32% were achieved, showcasing improved synthesis efficiency compared to conventional methods.

Packed-POCS with skin: A novel concept for the intensification of non-adiabatic catalytic processes demonstrated in the case of the Fischer-Tropsch synthesis

Laura Fratalocchi et al.

Summary: In this study, the heat transfer performance of a packed-POCS reactor was enhanced by adding an outer metallic thermally connected skin to the conductive cellular internals, achieving outstanding performances with a highly active Co/Pt/Al2O3 catalyst. The presence of the skin significantly improved thermal contact between the reactor wall and the cellular structure, leading to better temperature control inside the reactor and enabling new operating windows.

Kinetic study of phenol hydroxylation by H2O2 in 3D Fe/SiC honeycomb monolithic reactors: Enabling the sustainable production of dihydroxybenzenes

Gonzalo Vega et al.

Summary: The study investigated the chemical kinetics of phenol hydroxylation to produce dihydroxybenzenes using a 3D printed monolithic reactor. The experiments showed that the hydroxylation reaction mechanism involved three elementary reactions, leading to the formation of dihydroxybenzenes with a selectivity above 99% at 80 degrees Celsius in Fe/SiC honeycomb monolithic reactors.

Monolithic Stirrer Reactors for the Sustainable Production of Dihydroxybenzenes over 3D Printed Fe/γ-Al2O3 Monoliths: Kinetic Modeling and CFD Simulation

Pablo Lopez et al.

Summary: This study evaluates the performance of a stirring 3D Fe/Al2O3 monolithic reactor in the liquid-phase hydroxylation of phenol using hydrogen peroxide. Both experimental and numerical investigations were conducted to validate the kinetic and CFD models. The results show that the reaction temperature affects the selectivity of phenol conversion to dihydroxybenzenes, while the initial H2O2 concentration mainly affects the conversion rate of phenol.

Enhanced Fluid Dynamics in 3D Monolithic Reactors to Improve the Chemical Performance: Experimental and Numerical Investigation

Asuncion Quintanilla et al.

Summary: Three-dimensional (3D) Fe/SiC monoliths with different cell geometries (square, troncoconical, and triangular) were used as catalytic reactors in the hydroxylation of phenol using hydrogen peroxide. The triangular cell monoliths demonstrated superior performance in hydrogen peroxide decomposition, phenol hydroxylation, and dihydroxybenzene production reactions. A computational fluid dynamic model validated with experimental results showed that the triangular cell monoliths induced an oscillating flow of the liquid phase and additional transverse flow between adjacent parallel channels, resulting in better overall performance compared to other geometries.

Highly Conductive Structured Catalytic Reactors for One-Step Synthesis of Dimethyl Ether

Inigo Perez-Miqueo et al.

Summary: Different structured catalytic reactors for direct DME synthesis were compared based on catalyst hold-up, thermal conductivity, and volumetric productivity. Coating method shows advantages over packed-bed monolith in terms of catalyst inventory per reactor volume, but completely filling a monolith with powder catalyst leads to a significant decrease in CO conversion. The nature and shape of the substrate have minimal impact on the CO conversion values and selectivity to different compounds.
