Abstract
As an important innovation in the field of chemical engineering, microreactor technology has shown unique advantages in the study of gas-liquid mass transfer and reaction kinetics due to its high efficiency of mass and heat transfer, precise control of reaction parameters and low sample consumption. This study focuses on the optimization of gas-liquid mass transfer process and in-depth analysis of reaction kinetics in microreactors, aiming to reveal the mechanism of gas-liquid interaction at micro scale and its impact on reaction efficiency, and provide theoretical support and experimental basis for the promotion of microreactor technology in industrial applications. In microreactors, gas-liquid mass transfer is one of the key factors affecting the reaction efficiency. In this study, the gas-liquid mass transfer performance in microchannels was systematically studied by designing and constructing various types of microreactors, such as me tal tube microreactor, capillary enzyme microreactor and optical microreactor based on Teflon AF 2400 tube. The experimental results show that the high specific surface area and short diffusion path of the microreactor significantly improve the gas-liquid mass transfer efficiency, so that the reactants can quickly reach the reaction interface and participate in the reaction. At the same time, a variety of experimental methods, such as online monitoring, spectral analysis and mass spectrometry characterization, were used in this study to comprehensively monitor and deeply analyze the gas-liquid mass transfer process in the microreactor.
