In this study, the absorption properties of CO2 in seven different solid amine absorbents were measured. The specific characteristics, such as absorption capacity, absorption/desorption rate, cyclic capacity, cycle decay effect, temperature of reaction in the absorber, and optimal conditions for the CO,) absorption process were measured. This absorption process occurred at two temperatures-either 296.15 or 313.15 K-while the desorption process temperature was raised to 348.15 K. The solid amines (TEPAN and E-100AN) demonstrated higher cyclic capacity than others under these conditions. Our testing showed high reproducibility for the CO2 capture of TEPAN and E-100AN in measuring their cyclic capacity. Diminished cyclic capacities were noted for the MEA and 194B materials, with measured drops at the third cycle of about 16.17% and 15.79% lower than those in the first cycle, respectively.
