The hydrophobic resin-based solid amine adsorbent was prepared by modifying porous materials with different-molecular-weight polyethyleneimine (PEI), by taking hydrophobic oily macroporous adsorbent resin as carrier. The specific surface area, pore structure, functional group structure and thermogravimetric properties of the resin-based solid amine adsorbent were characterized by N2 isothermal adsorption-desorption, infrared and thermal analysis. The effects of PEI loading, air humidity (30%~80%), adsorption time and multiple cycles on the adsorption performance of CO2 were investigated. The results show that, the hydrophobic resin-based solid amine adsorbent has good trapping performance for CO2 in dry air (air humidity is less than 50%). The SD300 resin-based solid amine adsorbent modified by 30%PEI can reach more than 90% of the total adsorption capacity after one hour adsorption in atmospheric environment. When the molecular weight of the PEI is 1 800, it shows high adsorption capacity and good cycle stability of adsorption and desorption, mainly due to the high pore size and its excellent high temperature resistance.
