Improved Methane Hydrate Formation Rate Using Treated Activated Carbon and Tetrahydrofuran

Inhibition effects of activated carbon particles on gas hydrate formation at oil–water interfaces

“…They commonly utilized large-size activated carbon particles (over 250 mm in diameter) and lled the pores with water. [12][13][14][15] On the other hand, this study utilized small activated carbon particles below 150 mm in diameter which are tightly packed, forming a layer at the interface between the oil and water phases to interrupt the diffusion of the hydrate slurry and guest molecules to the aqueous phase. The quantitative inhibition efficiency was measured via dissociation enthalpies which determined the amount of hydrate formation in high pressure micro differential scanning calorimetry.…”

Assessing thermodynamic models and introducing novel method for prediction of methane hydrate formation

“…Results of their study showed that methane hydrate formation rate and storage capacity increased effectively (Ganji et al 2007). Several studies focus on the rate of methane hydrate formation in presence of different chemicals and porous materials (Liang et al 2005(Liang et al , 2009aYan et al 2005;Ganji et al 2007;Park and Kim 2010;Babu et al 2013;Chari et al 2013;Pasieka et al 2013;Lim et al 2014, Siangsai et al 2014.…”

Investigation on the roles of activated carbon particle sizes on methane hydrate formation and dissociation

“…Recently, Siangsai et al (2014) demonstrated that the activated carbon treated by sulfuric acid was more effective than that treated by potassium hydroxide in the methane hydrate formation.…”
