Stability of mixed gas hydrates and mass transfer during formation, accumulation and destabilization: laboratory experiment and modeling
Gas hydrates are fascinating ice-like compounds made of water cages that retain various types of guest molecules. Natural gas hydrates on Earth form below the seafloor and permafrost and contain mainly methane (CH4). Methane from hydrate deposits could be considered as an energy resource. One possib...
