L.A. Stern S. H. Kirby J.C. Pinkston W.B. Durham S. Circone 2000 We performed rapid depressurization experiments on methane hydrate under isothermal conditions above 272 K to determine the amount and rate of methane evolution. Sample temperatures rapidly drop below 273 K and stabilize near 272.5 K during dissociation. This thermal anomaly and the persistence of methane hydrate are consistent with the reported recovery of partially dissociated methane hydrate from ocean drilling cores. application/pdf en Methane hydrate dissociation rates at 0.1 MPa and temperatures above 272 K text
