▎ 摘  要

NOVELTY - An accelerant comprises 0.01-2 %mass three-dimensional graphene macro powder and deionized water. USE - Accelerant for generating gas hydrate. ADVANTAGE - The accelerant has three-dimensional porous structure, increased specific surface area, and is prepared by a simple, environmentally-friendly and economical method suitable for industrial production. The accelerant can be used repeatedly and improves the hydrate generation rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the accelerant, which involves adding the graphene macro powder into deionized water, stirring, mixing uniformly, ultrasonically processing and dispersing.
