To improve the application of surfactants in methane hydrate formation, sodium dodecyl sulfate (SDS) was fixed on the surface of polystyrene nanospheres (named as SDS@PSNS). SDS@PSNS resulted in a shorter induction period of hydrate formation compared to SDS. With SDS@PSNS as a promoter, hydrates formed mainly at the bottom of the reactor with a much higher apparent density and higher methane consumption, and during the hydrate dissociation period, less foam was generated. In addition, the recycling experiments showed high stability and good recycling performance of SDS@PSNS in seven methane hydrate formation-dissociation cycles.
