The Effects of Cationic Type Ionic Liquids on Methane Hydrate Formation

Abstract:

The article has studied the effects of ionic liquids on the induction time of methane hydrate formation under different mass concentrations, temperatures and pressures. The results show: all the tested ionic liquids can postpone the induction time of hydrate forming. Among them, imimidazolium-based ones have the strongest ability; The concentrations of ionic liquids also have strong effects on the induction time, and 0.5% is optimal. In addition the inhibiting abilities of ionic liquid on the induction time change with different pressures and temperatures, but not obviously.
