Abstract
Abstract
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 nano-sheets 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 %.
