摘要	The porous AlO with large-pore volume was synthesized by azeotropic distillation with sodium aluminate and aluminum sulfate as raw materials, which was used as a support to impregnate polyethyleneimine (PEI) for preparing aluminum-based solid amine adsorbent. The CO adsorption performance and cyclic stability of the adsorbent were systematically investigated subsequently. The porous AlO supports with apore volume of 2.75 cm·gwere prepared by aging and azeotropic distillation processes under the optimal technological parameters, and then the superior grade adsorbent (60%PEI@AlO-4 h) with a saturation CO adsorption capacity of 194 mg·gwas prepared. In addition, the adsorbent had stable cyclic performance in inert desorption atmosphere and CO desorption atmosphere. After 10 cycles, the CO adsorption capacity of 60%PEI@AlO-4 h still retained 186 mg·g and 148 mg·g, with attenuation of less than 1% and 15.2%, respectively. This study can provide reference for developing low-cost and high-stability solid amine adsorbents.
