摘要

We studied the reformation processes for structure I (sI) (methane, carbon dioxide) and structure II (sII) (propane) gas hydrates experimentally and investigated the memory effects between sI and sII hydrates using a constant-volume system. During these experiments, the induction period for hydrate formation was observed. Moreover, we also found that there were obvious memory effects in secondary formation of sI gas hydrates as well as in alternate secondary formation of sI and sII gas hydrates.
