摘要：
In this paper, various amine-modified CO2 adsorbents were prepared by incorporating tetraethylenepenthamine (TEPA) onto SBA-15(P) by controlling dynamic impregnation process. The materials were characterized by X-ray diffraction (XRD), nitrogen adsorption/desorption, elemental analysis (EA) and Fourier transform infrared (FT-IR) experiments. Moreover, the adsorption capacities and cycle life were evaculated by CO2 temperature programmed desorption (CO2-TPD). Various characterization results indicate that the morphology and loading amount of TEPA on the support material were controlled by adjusting dynamic impregnation times. Under given conditions, there is an optimum dynamic impregnation times.
