Abstract
A hydrate formation promoter and the use thereof in methane storage. The hydrate formation promoter is a mixed aqueous solution including cyclopentane, sodium dodecyl sulfate and water, wherein a volume fraction of the cyclopentane is 5% to 23.4% and a mass fraction of the sodium dodecyl sulfate is 0.01% to 0.08%. The hydrate formation promoter can realize effective and rapid formation of methane hydrate at approximate room temperature (25° C.), and can remain stable at higher temperatures.
