چکیده
|
In this study, graphene nano-sheets were grown and synthesized on copper foils and the structure was analyzed with xrd, ftir and sem. after that, 1 wt% low-layer graphene nano-sheets were added to water and stabilized by sodium dodecyl sulfate (sds). prepared nano-fluid was then used in hydrate formation of natural gas at 1000 psig and 4 °c. the results were compared with a sds/water system and observed that graphene nanosheets had reduced the dissolution time 19.2 %, induction time 54.7 % and the amount of gas storage is increased 7.6 %. hydrate stability test showed that the hydrate stability is also increased 5.9 %.
