We examined the CO2 capture capacity of mesoporous MgO (325 mesh size, surface area = 95.08 ± 1.5 m2/g) as a potential pre-combustion CO2 sorbent. Our results show that 96.96 % of MgO was converted to MgCO3 at 350 °C and 10 bars CO2 pressure. The sorbent could be completely regenerated at 550 °C under argon flow. The sorption rate parameters such as surface area and pore size were investigated.
