1. In a reactor vessel containing a methane hydrate solid material, a process for separating carbon dioxide from a gas mixture comprising said carbon dioxide and methane, said process comprising the steps of:contacting said methane hydrate solid material with said gas mixture, forming carbon dioxide hydrate; andremoving said methane from said reactor vessel.2. A process in accordance with claim 1, wherein said carbon dioxide comprises at least about 30% by volume of said gas mixture.3. A process in accordance with claim 1, wherein at least a portion of said carbon dioxide hydrate is removed from said reactor vessel.4. A process in accordance with claim 3, wherein said carbon dioxide hydrate removed from said reactor vessel are decomposed, forming carbon dioxide and water.5. A process in accordance with claim 1, wherein a portion of said methane removed from said reactor vessel is used to form said methane hydrate solid material.6. A process in accordance with claim 1, wherein said reactor vessel comprises one of a fixed bed, fluidized bed and a moving bed of said methane hydrate solid material.7. A process in accordance with claim 1, wherein said methane hydrate solid material is interstitially incorporated in a particle bed.8. A process in accordance with claim 7, wherein said particle bed comprises sand.9. In a gas mixture comprising a more stable hydrate-forming gas and a less stable hydrate-forming gas, a process for separating said more stable hydrate forming gas from said less stable hydrate forming gas comprising the steps of:introducing a first hydrate solid material produced by said less stable hydrate forming gas into a reactor vessel;contacting said first hydrate solid material with said gas mixture, whereby said first hydrate solid material is displaced by a second hydrate solid material, said second hydrate solid material formed by said more stable hydrate forming gas; andremoving said less stable hydrate forming gas from said reactor vessel.10. A process in accordance with claim 9, wherein said more stable hydrate forming gas is carbon dioxide.11. A process in accordance with claim 9, wherein said less stable hydrate forming gas is methane.12. A process in accordance with claim 9, wherein at least a portion of said second hydrate solid material is removed from said reactor vessel.13. A process in accordance with claim 9, wherein a portion of said less stable hydrate forming gas removed from said reactor vessel is recycled to form said first hydrate solid material.14. A process in accordance with claim 9, wherein said first hydrate solid material in said reactor vessel is disposed in one of a fixed bed and a moving bed.
