Abstract
According to the present invention, equilibrium between the applied gas and an aqueous liquid is achieved at conditions suitable for the preparation of a chemical complex of gas hydrate, and the pressure is then rapidly reduced to effect a concurrent temperature reduction and the formation of nuclei of water ice distributed throughout the aqueous liquid. Reaction conditions are then reestablished to initiate and complete the formation of gas hydrate which is then frozen within a matrix of the aqueous liquid. The resulting product is characterized by a high gas content, prolonged storage stability suitable for commercial distribution in its frozen state, and a vigorous, uniform effervescence when placed in water.
