The synergy of spiral agitation and nano-promoters significantly enhances hydrate formation under mild conditions
Sluggish hydrate kinetics and low methane storage capacity give rise to the limitation of the application of hydrate-based solidified natural gas (SNG) technology. Here, we prepared two nano-promoters of -SO3-@PSNS and -COO-@PSNS, with which, methane hydrate formation in a spiral-agitated reactor un...
