木质素协同氧化石墨烯对甲烷水合物特性的影响
The effect of lignin-synergized graphene oxide on the properties of methane hydrate
摘要
Abstract
Objective To investigate the kinetic performance of a sodium ligninsulfonate-graphene oxide(SL-GO)system for natural gas storage under conditions of 277.15 K and 5 MPa.Method The study examines the surface tension,gas consumption,and reaction rate of the SL-GO system,comparing its performance in methane hydrate formation with that of a sodium dodecyl sulfate-graphene oxide(SDS-GO)system.Key kinetic indicators such as induction time,gas storage capacity,and t50 were analyzed for both systems.Result Under identical conditions,the SL-GO system significantly reduced the solution's surface tension.Although the gas storage capacity was comparable to that of the SDS-GO system,the SL-GO system exhibited an 83.77%reduction in induction time,a 60.95%decrease in the total hydrate reaction time,and a 30.18%reduction in the time needed to reach a methane consumption of 50 mmol.Additionally,we investigated the complete dissociation time of hydrates at room temperature.Due to the foamless dissociation of the SL-GO system,its dissociation time was 61%less than that of the SDS-GO system.Conclusion These kinetic properties demonstrate that the SL-GO system is a more effective and valuable kinetic promoter than the SDS-GO system.This study provides theoretical guidance for natural gas hydrate storage and transportation technologies.关键词
