| Outline of Final Research Achievements |
The purpose of the present study to reveal the dissolution behavior of liquid CO2 into water during CO2 hydrate formation and, and the molecular diffusion behavior of H2O and CO2 in the CO2 hydrate. As the result, a time change of the mass transfer coefficient of CO2 in water and CO2 solubility of in water were derived by directory visualized image. As the result of molecular dynamics simulation, molecular diffusion coefficients in the CO2 hydrate increased with increase in molecular defects. It indicates that the method can evaluate the coefficients quantitatively in CO2 hydrate is now developed.
