Document Type and Number:
WIPO Patent Application WO/2012/101740
Kind Code:
A1
Abstract:
The invention addresses the problem of providing a production method for gas hydrates that are suitable for long-term storage wherein the self-preservation of the gas hydrate is high, and decomposition of said gas hydrate can be significantly inhibited. The gas hydrate production method, which produces gas hydrates by reacting starting material water, which contains an ion resulting from dissociation of an electrolyte in solution as a substance having gas hydrate decomposition-inhibiting effects, with a hydrate-forming substance, is characterized in that sodium chloride is added as the electrolyte and the chloride ion concentration in the starting material water is 0.1 mol/m3 - 6.5 mol/m3.
