Microreactors: RTD and Mixing

This lecture covers the design and operation of microreactors, focusing on microreactor types, passive and active micromixers, and segmented flow. It discusses the advantages of segmented-flow microreactors, such as stability, rapid mixing, and high-throughput screening. The lecture also delves into the principles of slug flow, Taylor flow, and the mass transfer capabilities of gas-liquid and liquid-liquid systems in microchannels. Furthermore, it explores the RTD in microchannels, including the effects of radial dispersion, flow maldistribution, and the enhancement of Bo by secondary radial flow. The presentation concludes with examples of industrial microreactor systems and scale-up strategies.
