The excessive use of fossil energy has led to a continuous and gradual increase in global CO2 emissions,and climate warming has become the most serious environmental problem facing mankind.Metal-organic framework materials (MOFs) are ideal CO2 adsorbents and can be used for CO2 capture due to their excellent properties.In this paper,NbOFFIVE-1-Ni@PA CO2 composite adsorbent provided by Beijing University of Chemical Engineering was used to test the adsorption penetration curve of low concentration CO2 using a self-built fixed bed device,and the influence of flow rate,temperature,concentration,air humidity and bed thickness on the adsorption behavior was explored.Three kinetic models were used to fit the adsorption data,and the cyclic stability of NbOFFIVE-1-Ni@PA was also investigated.The results showed that with the increase of gas flow rate,the CO2 adsorption capacity of NbOFFIVE-1-Ni@PA increased first and then decreased.The dynamic CO2 adsorption performance of NbOFFIVE-1-Ni@PA was enhanced by decreasing adsorption temperature,increasing concentration,decreasing air humidity and increasing the bed height.Avrami model could better fit the experimental data,indicating that the adsorption of CO2 by NbOFFIVE-1-Ni@PA was a combination of physical and chemical adsorption.Finally,after 10 times of adsorption and desorption,the adsorption capacity of NbOFFIVE-1-Ni@PA only decreased by 4.5%,showing excellent reproducibility.
