With increasing concern about global warming, CCS (Carbon dioxide capture and storage) has attracted much attention as a promising technology for reducing emission. It is necessary to develop the cost-effective absorbents materials in order to rapid commercialize CCS technologies. In this work, he study for the promotion of absorption rate in capture system using metal nanoparticle were investigated. Three kinds of metal nanoparticle, cobalt, zinc, and nickel, were prepared by wet and dry method and effect of preparation method on the absorption rate of were compared. Among the tested using pH method, nickel nanoparticle prepared by wet method showed the most significant improvement of absorption rate. In case that metal nanoparticle is applied to CCS process, it is expected to be more efficient in capture process due to reduce the size of absorption tower.
