Effect of Single Walled Carbon Nanotubes on Natural Gas Hydrate Formation

Using co-mo/mgo catalyst, single walled carbon nanotubes with a diameter of 2 nmand a length of 10 µm were produced by chemical vapor deposition process andcharacterized by xrd, ftir and sem. synthesized single-walled carbon nanotubeswere dissolved in water to make a 1 w% solution and stabilized by adding sodiumdodecyl sulfate surfactant. the synthesized stabilized nanofluid was used in the gaseoushydrate formation at a temperature of 4?c and pressure of 1000 psig. the results werecompared with a water/surfactant control solution and it was found that carbonnanotubes have reduced the duration of dissolution process by 58.9% and duration ofthe induction process by 75.5%. in addition, the amount of gas entrapment and stabilityof the gas in the hydrate were increased by 13.6% and 18.2%, respectively.
