The formation and dissociation properties, the gas composition of gas hydrate synthesized from the mixed gas of air and carbon dioxide, were investigated to make clear the behavior and the structure. From the experiments and discussion, the following results are obtained.The formation and dissociation condition of gas hydrates formed from CO2-Air mixtures have close relation with the components of mixed gases, so that the temperature and pressure for the formation and dissociation can be estimated by the initial condition of mixed gases.Based on the result that the guest components in synthesized hydrate contain much higher concentration of CO2 than in the initial gas mixture, it was found that the hydration technique can be used for the accumulation of CO2 component in gas phase.From the direct observation of guest components using Raman Spectroscopy, it was shown that a lot of N2 component was trapped as guests in the structure of CO2 gas hydrate.The behavior and the control of CO2 gas hydrate in the sediments would be examined to clarify the fundamentals for the storage of CO2 gas hydrate, using a more realistic experimental apparatus simulated for the in-situ deep marine environment.
