Enhancement of carbon dioxide absorption rate with metal nano particles

With increasing concern about global warming, CCS (Carbon dioxide capture and storage) has attracted much attention as a promising technology for reducing CO2 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 CO2 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 CO2 were compared. Among the tested using pH method, nickel nanoparticle prepared by wet method showed the most significant improvement of CO2 absorption rate. In case that metal nanoparticle is applied to CCS process, it is expected to be more efficient in CO2 capture process due to reduce the size of absorption tower.
