1CO2-adsorption capacity given in milligram CO2 per gram adsorber material. 2Number of adsorption/desorption cycles for this material batch. 3Missing cycle numbers are not listed here because the corresponding experiments were conducted with different CO2-concentrations and/or humidity. 4CO2-adsorption capacity corrected for leakage according to Equation (1). 5Temperature used to regenerate material at 100 mbar for 1 hour prior to adsorption experiment. 6Standard deviation and arithmetic mean calculated only for experiments with adsorber fully regenerated at 100°C. |
