本研究测定了7种不同固体胺吸收剂对CO2的吸收性能。测定了吸收容量、吸收/解吸速率、循环容量、循环衰减效应、反应温度和CO2吸收过程的最佳条件等特性。吸附过程在296.15 K和313.15 K下进行，而解吸过程温度提高到348.15 K。在这些条件下，固体胺（TEPAN和E-100AN）表现出较高的循环容量。我们的测试表明，在测量TEPAN和E-100AN的循环容量时，它们的CO2捕获具有很高的再现性。MEA和194B材料的循环能力下降，在第三个周期测量的下降幅度分别比第一个周期低16.17%和15.79%。
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 CO2 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.
