Assessing geochemical approaches to removing CO2 from the atmosphere

这是一个化学工程博士研究项目。海洋碱化描述了几种最终增加海洋碱度以增强海水中CO2封存的方法，是一些更有前途的新兴NET（Renforth和亨德森，2017）。然而，过程理解，例如，矿物的溶解动力学和这些方法的环境影响知识是不完整的。我们将在不同规模和复杂性下进行一系列实验，以生成关于海水碱度稳定性的强大数据库。这还将包括开发提高海洋碱度的工程方法。

This is a PhD research project in Chemical Engineering. Ocean alkalinisation, which describes several approaches that all ultimately increase ocean alkalinity to enhance CO2 sequestration in seawater, are some of the more promising emerging NETs (Renforth and Henderson, 2017). However, process understanding, e.g., dissolution kinetics of minerals, and environmental impact knowledge of these approaches are incomplete. The PhD we will conduct a series of experiments at different scales and complexities to generate a robust data base on the stability of alkalinity in seawater. This will also include developing engineering approaches for increasing ocean alkalinity.
