Phase transformation of methane hydrate under high pressure
In situ Raman spectroscopy is employed to study the phase behavior of methane hydrate at high pressure. The structure 1 of methane hydrate can be maintained up to 950 MPa at 299 K. The transformation of structure I< --- >structure H+water+CH4 occurs at 880 MPa and 323 K. The structure H of met...

Summary: | In situ Raman spectroscopy is employed to study the phase behavior of methane hydrate at high pressure. The structure 1 of methane hydrate can be maintained up to 950 MPa at 299 K. The transformation of structure I< --- >structure H+water+CH4 occurs at 880 MPa and 323 K. The structure H of methane hydrate, however, decomposes to methane and water at 960 MPa and 348 K. The initiation mechanism of methane hydrate sI is also discussed. (C) 2005 American Institute of Physics. Physics, Atomic, Molecular & Chemical SCI(E) EI PubMed 4 ARTICLE 2 024714 122 |
