The CO2 adsorption performance of solid adsorbents prepared by impregnation of primary and secondary amines into meso/macroporous silica materials with a bimodal pore size distribution is evaluated. Monoethanolamine (MEA), diethylenetriamine (DETA), triethylenetetramine (TETA), tris(2-aminoethyl)amine (TAEA), tris(3-aminopropyl)amine (TAPA), 1,3-diamino-2-propanol (DAP), tetrakis(aminomethyl)methane (TAMM) and linear polyethyleneimine (PEI) were immobilized into silica supports with high loading levels (40–60 wt%). The DETA-impregnated adsorbent at the optimal loading (51.7 wt%) exhibited the highest adsorption capacity of 6.78 mmol/g (29.9 wt%) under pure CO2 flow. CO2 adsorption performance was measured in a fixed bed reactor equipped with the temperature sensor. The influence of the CO2 content in the gas mixture and flow rate on the adsorption temperature and adsorption capacity was studied.
