Procedure

Heating a slurry with the initial composition of 50 ml water, 38.18 g KHCO3, and 23.65 g K2CO3 at 125.5° C. and 1.8 atm. produced 33.67 g K2CO3 and 10.72 g CO2, and the pH in the solution was 11.35. The total energy demand was estimated to be 2808 kJ/kg CO2, including 1119 sensible heat, 210 latent heat, and 1479 enthalpy.
