이산화탄소와 산화칼슘의 고온 광물탄산화 반응특성에 관한 연구

As a part of CCUS (Carbon Capture, Utilization, and Storage) technology, mineral carbonation technology (MCT) has received research attention. Through MCT, 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 CO 2 but also stabilizes heavy metal components contained in industrial byproducts. Therefore, interest in MCT research using industrial byproducts has gradually increased, and so it was evaluated as an eco-friendly byproduct treatment method. The aim of this research was the process optimization to find optimum experimental temperatures and reaction types in high-temperature carbonation, which is one of the MCT technologies. All experiments were conducted using fluidized and fixed-type reactors to obtain optimal reactor. The reaction temperatures were determined to be between 550℃ and 750℃, while CO 2 and CaO reaction times were controlled by gas flow rates using a mass flow controller.
