Clathrate hydrates have advantage for storing gas. So, it is expected to more effectively separate and store CO2, one of the green-house gases, after increasing the surface area of water by dispersing with hydrophobic silica nanoparticle having repulsive properties with water. Therefore, I investigated CO2 hydrate formation rate and storage capacity as changing the size of hydrophobic silica powder, mixing ratio, and dispersion method. Also, I observed how the hydrate equilibrium varies in nano-size space influencing on diffusion of guest gas and formation of hydrate cages. |
