Ion-Exchanged Calcium from Calcium Carbonate and Low

1996-3-20 · Interactions between CaCO3 and low-rank coals were examined, and the steam gasification of the resulting Ca-loaded coals was carried out at 973 K with a thermobalance. Chemical analysis and FT-IR spectra show that CaCO3 can react readily with COOH groups to form ion-exchanged Ca and CO2 when mixed with brown coal in water at room temperature.
