Effect of Additives on CO₂ Adsorption of Polyethylene Polyamine-Loaded MCM-41.

ABSTRACT: Organic amine-modified mesoporous carriers are considered potential CO₂ sorbents, in which the CO₂ adsorption performance was limited by the agglomeration and volatility of liquid amines. In this study, four additives of ether compounds were separately coimpregnated with polyethylene polyamine (PEPA) into MCM-41 to prepare the composite chemisorbents for CO₂ adsorption. The textural pore properties, surface functional groups and elemental contents of N for MCM-41 before and after functionalization were characterized; the effects of the type and amount of additives, adsorption temperature and influent velocity on CO₂ adsorption were investigated; the amine efficiency was calculated; and the adsorption kinetics and regeneration for the optimized so
