Dissociation condition measurements of methane hydrate in confined small pores of porous glass
Article Abstract:
The effects of confined small pores on methane-hydrate dissociation are investigated. Results show downward shifts in the dissociation temperature of porous glasses with pores between 100 and 500 angstroms in diameter. The heat of the methane-hydrate dissociation is small compared to bulk hydrates in pores less than 300 angstroms in diameter. Changes in dissociation conditions of methane hydrates are attributed to changes in water activity.

Do montmorillonite surfaces promote methane hydrate formation? Monte Carlo and molecular dynamics simulations
Article Abstract:
Monte Carlo and molecular dynamics simulations are carried out in this study to examine the condition of the stable methane clathrates. On the basis of these simulations, methane hydrate is proposed to occur in natural sediments with a portion of a clay mineral surface actively involved in promoting clathrate formation.
