The Effects of Cationic Type Ionic Liquids on Methane Hydrate Formation

摘要

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.
