A variety of CO2 capture technologies have been developed to reduce CO2 responsible for global warming. In this study, various combination of metal salt in group I and II were impregnated onto MgO for CO2 capture at 573 – 673 K. The obtained sorbents have been characterized with XRD, SEM and nitorgan adosrption-desorption method. The CO2 adsorption ability of NaNO3 impregnated MgO was found to have a high adsorption up to 30wt%, but its adsorption capacity was not stable and declined with the repeated capture-generation cycles. While NaNO3 and Ba(NO3)2 impregnated into MgO showed the stable adsorption capacity in the cyclic measuement. |
