Methane hydrate formation and dissociation behaviors in montmorillonite
The methane hydrate formation and the methane hydrate dissociation behaviors in montmorillonite arc experimentally studied. Through the analyses of the microstructure characteristic, the study obtains the porous characteristic of montmorillonite. It is indicated that methane hydrate in montmorilloni...
