Abstract

A hydrate decomposition inhibiting composition, a coupling enhanced solid hydrate, and a method for improving the solid hydrate storage and transportation stability relating to the technical field of natural gas safety storage and transportation are provided. The hydrate decomposition inhibiting composition contains a carboxymethyl starch salt and an alkyl glycoside surfactant. The composition improves the interface stability of the hydrate phase boundary and the mechanical stability of the hydrate and enhance the strength of the hydrate crystal interface since the colloidal solution formed by dispersing the sodium carboxymethyl starch and the alkyl glycoside surfactant in water can coat the surface of the hydrate to form a protective layer, thereby improving the structural stability of the hydrate. Therefore, the composition inhibits the decomposition of the hydrate, reduces the decomposition rate of the hydrate, and can further reduce the decomposition amount of the hydrate.
