Methane hydrate dissociation conditions in the presence of imidazolium based aqueous ionic liquid solutions including 1-buthyl-3-methylimidazolium methyl sulfate ([BMIM][MeSO4]) , 1-ethyl-3-methylimidazolium hydrogen sulfate ([EMIM][HSO4]) and 1-1-ethyl-3- methylimidazolium ethyl sulfate [EMIM][EtSO4] are investigated. The reliability of the experimental procedure in this work is demonstrated by comparing methane hydrate dissociation data in pure water with literature. The comparison between methane hydrate dissociation conditions in the presence/absence of ionic liquid solutions is shown. It is found that amongalkylsulfate-containing ionic liquids, the thermodynamic inhibition effects of two ionic liquids such as [EMIM][HSO4] and [BMIM][MeSO4] are better than that of [EMIM][EtSO4
