CO₂ Mineral Sequestration: Chemically Enhanced Aqueous Carbonation of Serpentine

Abstract

Abstract As one of the greenhouse gases, it is essential to reduce CO 2 emissions in order to stabilize CO 2 levels in the atmosphere while allowing the continued use of fossil fuels. Abatement of CO 2 by mineral carbonation has been proposed as one of the most promising methods for CO 2 emission control in the flue gas from coal‐fired power plants. However, little is known about the fundamental characteristics of CO 2 ‐mineral reactions. The overall goal of this study was to investigate the mechanisms of the aqueous reactions of CO 2 with Mg‐bearing minerals. Specifically, the focus was on the enhancement of the mineral dissolution.
