Abstract: Carbon dioxide sorption using a metal oxide-alkali metal carbonate sorbent typically requires a relative humidity of greater than 25% in order to obtain reaction rate constants of about 2.0 to 3.0 sec..sup.-1 (see Equation 6). The incorporation of alkali halide salt into the metal oxide-alkali metal carbonate sorbent maintains rate constants of about 2.0 to about 4.0 sec..sup.-1 at relative humidities below 25%. Therefore, the hygroscopic alkali halide salt attracts water, thereby providing the necessary hydroxide ions for enhanced absorption at low relative humidities.
