CO2 sequestrations in a combustion using a fossil fuel are major issues of the environment. A mineral carbonation is one of method which is attractive researchs in advanced technology. A sepiolite, magnesium-rich mineral, is selected in this study. It was treated various conditions. The heat treated sepiolite was measured by ICP, XRD, FT-IR, SEM and XPS in order to analyze crystallochemical and spectroscopic property. A OH- group in sepiolite was removed by heat treatments. The proper time and temperature of heat treatments was known as the analysis. |
