摘要
近年来,涉及微液滴的两相反应备受关注,这是因为微液滴具有独特的催化和加速反应的能力,通过利用微米级界面的化学和物理效应,这些反应通常不会在标准条件下发生。在这项工作中,我们创新性地开发了一种按比例放大的微液滴反应器,用于二氧化碳的高效资源利用。反应液以雾状(d32 < 20 μm)喷出,促进了与气态二氧化碳的完全接触和反应。我们探索了喷雾特性和反应器参数对从 CO2 中连续生产有机碳酸盐的影响。值得注意的是,与传统的高压反应器相比,微滴反应器的反应效率至少提高了 10 倍。此外,我们还利用计算流体动力学(CFD)模拟优化了工艺条件和连续生产参数,系统地研究了扩大装置规模的影响。在此,我们以可靠的数据为支持,介绍了在放大应用中利用微液滴反应器进行二氧化碳转化的见解。
Scale-up of Microdroplet Reactors for Efficient CO2 Resource Utilization
Two-phase reactions involving microdroplets have gained significant attention in recent years due to their unique ability to catalyze and accelerate reactions that typically do not occur under standard conditions by leveraging chemical and physical effects at the micrometer-scale interface. In this work we have innovatively developed a scaled-up microdroplet reactor for the efficient resource utilization of CO2. The reaction liquid is sprayed in the form of mist (d32 < 20 μm), facilitating complete contact and reaction with gaseous CO2. We explored the effects of spray properties and reactor parameters on the continuous production of organic carbonates from CO2. Remarkably, the microdroplet reactor enhanced the reaction efficiency by at least 10-fold compared to conventional high-pressure reactor setups. Additionally, we used computational fluid dynamics (CFD) simulations to optimize the process conditions and continuous production parameters, systematically studying the effects of scaling up the device. Here, we present insights into the utilization of microdroplet reactors for CO2 conversion in scaled-up applications, supported by robust data.
