 CO2 (carbon dioxide) fixation by applying new chemical absorption-precipitation methodsSangwon Park, Min-Gu Lee and Jinwon Park Energy, 2013, vol. 59, issue C, 737-742 Abstract: CO2 (carbon dioxide) is the most common greenhouse gas and most of it is emitted from human activities. The methods for CO2 emission reduction can be divided into physical, chemical, and biochemical methods. Among the physical and chemical methods, CCS (carbon capture and storage) is a well-known reducing technology. However, this method has many disadvantages including the required storage area. In general, CCS requires capture and storage processes. In this study, we propose a method for reusing the absorbed CO2 either in nature or in industry. The emitted CO2 was converted into CO32− using a conversion solution, and then made into a carbonate by combining the conversion solution with metal ions at normal temperature and pressure. The resulting carbonate was analyzed using FT-IR (Fourier transform infrared spectroscopy) and XRD (X-ray diffraction). We verified the formation of a solid consisting of calcite and vaterite. In addition, the conversion solution that was used could be reused in the same process of CCS technology. Our study demonstrates a successful method of reducing and reusing emitted CO2, thereby making CO2 a potential future resource.
