Sequestration of carbon dioxide in cement industry by mineralization with olivine

Abstract The cement industry produces approximately 4.1 billion tones of cement annually and is responsible for nearly 8% of global CO 2 emissions. Within this production chain, clinker manufacturing accounts for almost 90% of process-related emissions, with about 60% emitted from the calcination of raw materials. Consequently, decarbonizing the calcination step is an important step. Olivine, one of the most abundant naturally occurring minerals, offers thermodynamically favorable conditions for CO 2 capture and can form stable carbonates suitable for use as Supplementary Cementitious Materials (SCMs). This study examines the influence of various presence of gases on CO 2 sequestration efficiency using olivine. The results indicate some gases influence the adsorption of CO 2 . These findings will inform the future integration of olivine-based CO 2 sequestration within the clinker production process.
