摘要

利用天然气水合物储存和运输天然气受到了研究者关注。然而，水合物存在生成条件苛刻、生成速率慢和储气量低等问题，限制了该技术的应用。采用全氟己基磺酸钾（PHS）与氧化石墨烯（GO）复配的促进剂，在277 K、6 MPa条件下，开展了甲烷水合物生成实验，研究了其动力学特性。结果表明，不同浓度复配促进剂用于水合物生成，诱导时间最短为3 min（0.2 g/L GO + 10 mmol/L PHS），相比纯水体系诱导时间（221 min）显著缩短；储气量最高为158 mL/mL（0.2 g/L GO + 10 mmol/L PHS），相比纯水体系储气量增大了690%，相比0.2 g/L十二烷基硫酸钠（SDS）作为促进剂储气量增大了28%。回收利用复配促进剂（0.2 g/L GO+10 mmol/L PHS），5次循环过程中储气量均可保持在120 mL/mL。

Abstract

The storage and transportation of natural gas using gas hydrates have garnered attention from researchers. However

the application of this technology is limited by challenges such as harsh formation conditions

slow formation rates

and low gas storage capacity. A co-promoter composed of potassium perfluorohexanesulfonate (PHS) and graphene oxide (GO) was employed to investigate the kinetics of methane hydrate formation under conditions of 277 K and 6 MPa. The results indicate that using different concentrations of the co-promoter significantly reduces the induction time

with the shortest induction time of 3 min (0.2 g/L GO + 10 mmol/L PHS) compared to 221 min for the pure water system. The maximum gas storage capacity achieved was 158 mL/mL (0.2 g/L GO + 10 mmol/L PHS)

which represents a 690% increase over the pure water system and a 28% increase compared to using 0.2 g/L sodium dodecyl sulfate (SDS) as a promoter. Furthermore

the co-promoter (0.2 g/L GO + 10 mmol/L PHS) demonstrated good recyclability

maintaining a gas storage capacity of 120 mL/mL during five cycles.
