摘要: Silicate minerals such as olivine (Mg2SiO4) and serpentine [Mg3(OH)4(Si3O5)] can react with CO2 to form mineral carbonates permanently store CO2. Despite significant advancements in carbon mineralization, major discrepancies the reported kinetics exist because of inconsistencies among various experimental methodologies, heterogeneity aging minerals, inadequate fast morphological data probe reaction mechanisms. In this work, it was found that aged freshly ground produce very different carbonation yields. A new cleaning protocol remove fines (<5 μm) developed. Fast slow dissolution regimes were distinguished using a custom-built differential-bed reactor. Mineral carbonate formation bubble-column reactor described. Different analyses evaluated for accurate estimation extent mineralization. Therefore, study focused on development an framework analy...
