| 英文摘要 | using co2-ch4 (carbon dioxide methane) replacement to produce ch4 from ngh (natural gas hydrate) is not only a new ch4 production technology but also a direct way to disposal co2 by co2 hydrates. although there are many studies focusing on the mechanism of ch4 replacement in hydrates by co2, the mechanism of the replacement is still not clear. in this work, the replacement process and hydrate structure change are tracked and investigated by raman and nmr (nuclear magnetic resonance) spectra. by comprehensively analyzing the raman and nmr spectra, we infer the mechanism of the replacement and the hydrate structures. conclusions are drawn as, on one hand, ch4 molecules are fully replaced with the gas solid interface, but partly replaced in deeply inner hydrates by co2 molecules; on the other hand, the co2 hydrate and ch4 hydrate coexist in a type of structure i (sl) and there is no structure transformation during the replacement. the research results are important to further confirm the mechanism of the replacement and reveal factors restraining efficiency of the ch4 production.
