Abstract

Amine-functionalized clover leaf-shaped Al ₂O ₃ extrudates (CA) were prepared for use as CO ₂ sorbent. The as-synthesized materials were characterized by N ₂ adsorption, XRD, SEM and elemental analysis followed by testing for CO ₂ capture using simulated flue gas containing 15.1% CO ₂. The results showed that a significant enhancement in CO ₂ uptake was achieved with the introduction of amines into CA materials. A remarkably high volume-based capacity of 70.1mg/mL of sorbent of this hybrid material suggests that it can be potentially used for CO ₂ capture from flue gases and other stationary sources, especially those with low CO ₂ concentration. The novel adsorbent reported here performed well during prolonged cyclic operations of adsorption-desorption of CO ₂.
