摘要：
Methane gas hydrate (MH) formation/dissociation were investigated in nano silica and water system in a non-stirred reactor. The MH yield was significantly improved in the presence of nano silica. The overall methane hydrate conversion (>= 80%) was achieved by optimizing the nano silica to water ratio. Two-stage dissociation was observed after a rapid de-pressurization. Methane gas intake of this system was steady for multiple freezing-thawing cycles signifying improved stability for methane gas storage. (c) 2012 Elsevier B.V. All rights reserved.
