摘要

Abstract

A novel solid support adsorbent for CO

capture was developed by loading pentaethylenehexamine (PEHA) on commercially available mesoporous molecular sieve MCM-41 using wet impregnation method. MCM-41 samples before and after PEHA loading were characterized by X-ray powder diffraction

adsorption/desorption

thermal gravimetric analysis and scanning electron microscope to investigate the textural and thermo-physical properties. CO

adsorption performance was evaluated in a fixed bed adsorption system. Results indicated that the structure of MCM-41 was preserved after loading PEHA. Surface area and total pore volume of PEHA loaded MCM-41 decreased with the increase of loading. The working adsorption capacity of CO

could be significantly improved at 60% of PEHA loading and 75℃. The effect of the height of adsorbent bed was investigated and the best working adsorption capacity for MCM-41-PEHA-60 reached 165 mg·(g adsorbent)

-1

at 75℃. Adsorption/desorption circle showed that the CO

working adsorption capacity of MCM-41-PEHA kept stable.
