Performance of CO₂ Adsorption with MEA-AN Modified Solid Adsorbent

Abstract:

CO₂ solid adsorbent was prepared through impregnating acrylonitrile (AN) modified monoethanolamine (MEA) into structurally disordered mesoporous silica (M) pore channel. Its structure was characterized by X-ray diffraction characterization (XRD), N₂ adsorption-desorption tests (BET), Transmission electron microscopy (TEM) and Fourier transform infrared (FT-IR). The capacity of CO₂ adsorption and desorption were measured and evaluated by comparison with MEA-impregnated material. The results showed that the capacity of M-MN-50 reached up to 125.8 mg·g^-1 and could desorb completely at the temperature of 40 °C by vacuum with 2.6 KPa. The hybrid material exhibited satisfactory performance during 10 turnovers.
