Scaling up of 3D printed and Ni/Al₂O₃coated reactors for CO₂methanation

Abstract

This study presents the innovative Ni/alumina coated structured metal supports manufactured by 3D-printing technique and their methane productivity comparison in two different experimental set-ups: a lab scale reactor and a mini-pilot scale reactor.

The rise of continuous flow biocatalysis – fundamentals, very recent developments and future perspectives

“…187 The fusion between 3D printing and continuous flow biocatalysis took place few years ago when researchers started to ask themselves how additive manufacturing's pros enhance continuous flow chemistry. 188,189 Since then, additive manufacturing successfully overcome deficits in the field of continuous flow chemistry with respect to manufacturing of solid supports with immobilized enzymes. Some promising developments have been achieved recently and many studies focus on the development of 3D-printed carriers.…”

“…With its cost-efficiency it is indeed possible to assemble reactors with diverse and complex structures, channels and porosities. 189,[197][198][199] Moreover, each 3D-printed component can be modified easily (completely or partially) compared to the first design draft, if necessary, favoring a simple trial-and-error development process. 192 This principle can be implemented when CAD modeling is combined with computational fluid dynamics (CFD), where it simplifies the development and optimization of the reactor design and allows digital visualization and understanding of the entire process.…”

A Review on New 3-D Printed Materials’ Geometries for Catalysis and Adsorption: Paradigms from Reforming Reactions and CO2 Capture

“…Michelle Kramer et al [183] used additive manufacturing in producing a monolithic-structured support for catalyst substrate. They believe that 3D printing allows for tailoring the heat and mass transfer properties, overcoming the obstacle of conventional monolith structures having issues with heat transfer and natural convection of their walls.…”

“…Simge Danaci et al [183] utilized robocasting 3-Dfiber deposition (3DFD) [184] to fabricate metal support structures and to coat it subsequently with Ni/Al 2 O 3 as a reactor for methanation. The 3D printed support structure coated with Ni has been tested in a single tube over a variety of reported reaction conditions.…”

3D printed Ni/Al2O3 based catalysts for CO2 methanation - a comparative and operando XRD-CT study

“…53 Previous studies of the authors on Ni-alumina coated onto 3D printed metals supports provided further impetus to the development of the directly printed Ni-alumina based monolithic structures for methanation that are presented herein. 54,55 In this work direct write has been employed for the 3D co-printing of Ni-alumina catalysts to mimick Ni-alumina coated monoliths/honeycombs. By directly patterning the honeycomb-like (multichannel) monolithic catalysts with active materials and supports, a significantly higher degree of control has been achieved over the materials distribution, geometry, morphology and function.…”
