Roles of Activated Carbon and Tetrahydrofuran on Methane Hydrate Phase Equilibrium
This work studied the effects of activated carbon and tetrathydrofuran (5.56 mol % THF) on methane hydrate phase equilibrium and hydrate dissociation. The hydrate formation was carried out in the quiescent condition and close system at 4 °C. After completion of hydrate formation, the hydrate dissoci...
