Mineral Carbonation of Calcium and Carbon Dioxide

The Kyoto Protocol was adopted where various countries unified to fight global warming by reducing greenhouse gas concentrations in the atmosphere to a level that would prevent dangerous anthropogenic interference with the climate system. As a part of CCUS (Carbon Capture Utilization and Storage) technology, mineral carbonation technology (MCT) has caught attention in research as CO2 is chemically reacted with calcium-and/or magnesium-containing minerals to form stable carbonate materials which do not incur any long-term liability or monitoring commitments. Moreover, MCT using industrial byproducts not only captures CO2 but also stabilizes heavy metal components contained in industrial byproducts. The study focuses in optimization to find experimental temperature and reaction type in high- temperature carbonation. All experiments were conducted using fluidized and fixed type reactor. The reaction temperature was determined as 450~650 oC while CO2 and CaO reaction time was controlled by gas flow rate using mass flow controller.
