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 128.3° C. and 1.2 atm. produced 31.77 g K2CO3 and 10.12 g CO2, and the pH in the solution was 11.19. The total energy demand was estimated to be 2926 kJ/kg CO2, including 1225 sensible heat, 223 latent heat, and 1479 enthalpy.
