Cyclic CO2 Capture Performance of Carbide Slag Parametric

Aug 18, 2012Abstract. In this work, CO 2 capture performance of carbide slag has been investigated in a thermogravimetric analyzer (TGA). Effects of operation parameters including particle size, reaction temperature and reaction duration on CO 2 capture capacity were studied. The experimental results indicate that the increase of particle size ranging from 80 to 180 μm has a positive effect on the CO 2

Magnesian calcite sorbent for carbon dioxide capture

Magnesian calcite with controlled properties was synthesized for the removal of carbon dioxide. The results from characterization, reactivity and CO2 capture capacity for different synthesis conditions are reported. The magnesian calcite samples (CaCO3MgCO3) were synthesized by the coprecipitation of specific amounts of commercially available CaO and MgO by carbon dioxide.
