Multi-walled carbon nano tubes effects for methane hydrate formation

Methane hydrate is considered an excellent way of transporting and storing natural gas in large quantities. However, when methane hydrate is formed artificially, the amount of consumed gas is relatively low due to a slow reaction rate between water and methane gas. Therefore, for the practical purpose in the application, the present investigation focuses on the rapid hydrate formation and the amount of consumed gas by adding MWCNT to pure water. The results show that when the multiwall carbon nano tubes of 0.004 wt% was added to pure water, the amount of consumed gas was about 300% higher than that in pure water and the hydrate formation time decreased at the low subcooling temperature.
