| Research Abstract |
To establish the preparation method of gas hydrates with the balance between the storage capacity and the formation and storage condition, the mechanism of the tuned large-cage occupancy of gases (tuning effect) under the existence ofadditives has been investigated. The present experimental results reveal that the important factors for the tuning effect are both the existence of mobile water molecules (quasi-liquid layer) at the ice surface and the competitive large-cage occupancy of gases and additives.
