This paper presents an innovative approach aimed at the efficient capture of low-carbon flue gas with a CO concentration of 25%–30% on a large scale and its subsequent fixation into economically valuable soda ash. This carbon-negative process entails a novel micro/nanofluid interface system (MIS) as a principal component. To gain a better understanding of the MIS and enhance its properties, we propose a new MIS compositional strategy that includes the formation mechanism of micro-interfaces, scale prediction and regulation methods, gas content enhancement mechanisms, property calculations, and examination of changes in reaction kinetic equations induced by the studied reaction. This compositional strategy not only unveils the intrinsic mechanisms that drive process intensification but also provides essential reference points for the MIS application on larger scales and in various fields, paving the way for its engineering applications.

基于微纳流体的低碳烟气中捕集CO2生产纯碱的负碳工艺：效果及增强机制


本文提出了一种创新方法，旨在大规模有效捕获 CO 浓度为 25%–30% 的低碳烟气，然后将其固定为具有经济价值的纯碱。这种负碳过程需要一种新型微/纳米流体界面系统（MIS）作为主要组成部分。为了更好地理解 MIS 并增强其性能，我们提出了一种新的 MIS 组成策略，包括微界面的形成机制、规模预测和调节方法、气体含量增强机制、性能计算和反应变化检查由所研究的反应引起的动力学方程。这种组合策略不仅揭示了驱动过程强化的内在机制，而且为MIS在更大规模和各个领域的应用提供了重要的参考点，为其工程应用铺平了道路。
