CO2 Sorption and Regeneration Properties of K2CO3/Al2O3-Based Sorbent at High Pressure and Moderate Temperature

In this study, the CO2 sorption mechanisms and regeneration properties of alumina-based sorbent using K2CO3 loading under high-pressure moderate temperature conditions were examined. To investigate mechanism sorption, a zirconium-based was compared with an sorbent. The capture capacities PAI10, 20, 30, 40 32.3, 63.0, 95.4, 124.5 mg CO2/g sorbent, respectively. we performed XRD, TG/DTG, FTIR analyses after in presence 10 vol% H2O each at 200 °C 20 atm. For PAI10–40 sorbents, KHCO3 KAl(CO3)(OH)2 phases observed by TG/DTG analysis. PAI-x it confirmed that captured is desorbed completely below 400
