Outline of Final Research Achievements

To develop efficient and environment-friendly carbon dioxide capture technology using clathrate hydrate, optical observation experiments and thermodynamic simulations were performed. The optical observation revealed that the crystal growth behavior depends on the thermodynamic conditions of the system. The reliability of thermodynamic simulations was confirmed.
