Mineral carbonation of high-calcium fly ash under elevated pressure and temperature
Fly ash from combustion of lignite in a Polish power plant was carbonated with CO2 under lab. conditions at 298-343 K and under 0.4-1.5 MPa. The CO2 uptake increased with increasing pressure. Both phys. adsorption of CO2 and chem. reaction with the fly ash were obsd.
