地质固碳是一种立即可用的、技术上可行的方法，可大幅度减少向大气排放的二氧化碳。为了开发稳定的地质封存技术，本研究提出了一种在多孔结构中使用纳米级CO2液滴的新方法。通过在注入前将CO2从连续相转变为纳米级液滴，可以减小浮力效应。在这项研究中，实验的重点是纳米尺寸的CO2液滴的形成，它们的时间演变，以及它们在多孔介质中的行为。实验结果表明，纳米级CO2液滴的稳定地质封存的高潜力。
Geological sequestration is an immediately available and technologically feasible method to achieve substantial reductions in carbon dioxide (CO2) emissions to the atmosphere. To develop a stable geological storage technique, this study proposes a new method using nanosized CO2droplets in a porous structure. The buoyancy effect can be reduced by changing the CO2from a continuous phase to nanosized droplets before injection. In this study, the experiments focused on the formation of nanosized CO2droplets, their time evolution, and their behavior in porous media. The experimental results suggested the high potential of the nanosized CO2droplets for stable geological storage.
