ABSTRACT:
Water ice is contacted with a conditionally-stable-hydrate-forming gas to form a hydrate complex of the gas, and is then enrobed in a frozen aqueous liquid to increase structural and storage stability. According to a preferred embodiment, carbon dioxide hydrate is formed by contacting solid water ice with gaseous carbon dioxide; the hydrate is wetted with a carbon-dioxide-saturated aqueous liquid; and the resulting wetted hydrate is frozen.
