Potassium Carbonate → Carbon Dioxide

Participants

Reaction Steps

Heating a slurry with the initial composition of 50 ml water, 38.18 g KHCO3, and 23.65 g K2CO3 at 125.8° C. and 1.6 atm. produced 37.27 g K2CO3 and 11.87 g CO2, and the pH in the solution was 11.6. The total energy demand was estimated to be 2683 kJ/kg CO2, including 1014 sensible heat, 190 latent heat, and 1479 enthalpy.
