Abstract

Sorption isotherms, which describe CO2 storage capacity of the host rock, are important for estimating the CO2 sequestration potential of geological formations. In this study, the sorption capacity of a sandstone and granite were evaluated experimentally by using a gravimetric method, and the experimental data corrected for the volume of sorbed CO2 phase were compared with storage models (adsorption monolayer, solubility and pore-filling models). The sorption measurement results indicated that CO2 sorption behavior could take place onto silica minerals in CO2-water-rock system, and it further indicated that CO2 sorption onto rocks may play an important role in storing CO2 in subsurface rock masses.
