Natural gas hydrates are ice-like crystalline and non-stoichiometric compounds formed by hydrogen bonds from water molecules when methane is trapped inside. Gas hydrates have received much attention not only as a new natural energy resource but also

The slow formation rate and low conversion of water to hydrates hinder the production of gas hydrate storage and transportation of gas in industry. The presence of Tetrahydrofuran (THF) in the gas hydrate system was discovered that it could reduce th
