Microstructured Reactors for Catalytic Reactions

Abstract

This review addresses the catalytic reactions performed in microstructured reactors, which are more and more recognized in recent years as a novel approach for chemistry and chemical process industry. They are particularly suited for highly exothermic and fast reactions allowing temperature control and isothermal operation. A brief evaluation of the advantages for gas-phase, liquid-phase, and gas-liquid-solid reactions carried out in miniaturized devices is discussed. Alternative designs to achieve microstructured fluid patterns, besides microfabrication, are also described. #

Liquid–liquid two-phase flow patterns and mass transfer characteristics in rectangular glass microreactors

“…Therefore, microreactors allow an intensification of the fast and strongly exothermic or endothermic reactions as shown recently by Lomel et al (2006) for the case of organometallic synthesis. Other important characteristics of MSR are the narrow residence time distribution and the easy scaleup with inherent reactor safety (Kiwi-Minsker and Renken, 2005).…”

“…Nevertheless, heat and mass transport limitations can easily occur and significant pressure drop can arise [14,16].…”

On-Paper Synthesis of Silver Nanoparticles for Antibacterial Applications

“…However, the random packing of catalyst powders into the reactor inevitably causes a highpressure drop and fluid bypassing, resulting in critical inefficiency of the catalytic reforming process. For that reason, one area of increasing attention has been the development of structured catalysts with micrometer-scale pores that have effective diffusion of heat and reactants, particularly in flow-type reactors (Kiwi-Minsker & Renken, 2005). As previously described, an inorganic paper matrix prepared using our established papermaking technique has a unique porous microstructure derived from ceramic fiber networks (Fig.…”
