Then, the supports such as activated carbon and aluminum oxide were impregnated with different concentrations of sodium carbonate solution and the repetitive carbon dioxide sorption characteristics were observed. The experimental parameters included carbonation temperature, carbonation time, calcination temperature, calcination time, carbon dioxide concentration and the kinds of support with impregnation concentrations of sodium carbonate. Conversions for the carbonation/calcination of sodium carbonate were evaluated under different operating conditions. The empirical models for the decay of the carbon dioxide capture capacity in multiple carbonation/calcination cycles were presented in comparison with the experimental results.
