Abstract：The effects of the K2CrO4 concentration, CO2 pressure and temperature on equilibrium concentration of KHCO3 were investigated respectively during the K2CrO4 carbonation with kinetic equations derived. Experimental results showed that the equilibrium concentration of KHCO3 was above 225 g/L under the optimal conditions of 40% K2CrO4 concentration, 0.6 MPa CO2 pressure and 18oC temperature. The kinetic equation was derived and its parameter was confirmed by experimental data .
