摘要
Natural gas hydrate is a kind of clean energy with potential huge reserves. Hydrate researches gradually extend to nano- and micro-scale recently. Nano science has been a part of hydrate researches, including occurrence, gas production and hydrate based technologies of downstream such as gas storage and separation. The common key is heat and mass transfer of hydrate formation and dissociation on the surface, inside and between nanomaterials. From 9th international conference on gas hydrates (ICGH9) as point of penetration in this paper, it reviews nano-scale studies on occurrence and gas production of marine gas hydrates, as well as downstream utilizations of gas hydrate technology. The results show that study of heat and mass transfer inside nanomaterial during hydrate formation and dissociation is needed to be developed. There is a blank area that accumulative effect of micro-nanomaterial during hydrate formation and dissociation. These questions have become bottleneck of gas hydrate occurrence and production. In the future, researches should focus on heat and mass transfer inside nanomaterial during hydrate formation and dissociation and use this as a link to systematively study occurrence and production of natural gas hydrates.
