Abstract: | Amine-functionalized clover leaf-shaped Al2O3 extrudates (CA) were prepared for use as CO2 sorbent. The as-synthesized materials were characterized by N2 adsorption, XRD, SEM and elemental analysis followed by testing for CO2 capture using simulated flue gas containing 15.1% CO2. The results showed that a significant enhancement in CO2 uptake was achieved with the introduction of amines into CA materials. A remarkably high volume-based capacity of 70.1 mg/mL of sorbent of this hybrid material suggests that it can be potentially used for CO2 capture from flue gases and other stationary sources, especially those with low CO2 concentration. The novel adsorbent reported here performed well during prolonged cyclic operations of adsorption-desorption of CO2. |
