TL;DR: The experimental results obtained in this study provide the physicochemical background required for understanding selective partitioning and distributions of guest gases in the QAS semiclathrate hydrates and for investigating the feasibility of a semicLathrate hydrate-based precombustion CO2 capture process.

TL;DR: In this paper, the feasibility of the hydrate-based pre-combustion capture of carbon dioxide in the presence of a thermodynamic promoter and porous silica gels was examined through stability condition measurements, gas uptake measurements, and microscopic analyses.

TL;DR: The overall results given in this study are useful for understanding the fundamental guest gas enclathration behavior in the double semiclathrates.

TL;DR: In this paper, the authors examined the CH 4 -CO 2 swapping phenomenon occurring in gas hydrates and its potential application to CO 2 sequestration through thermodynamic equilibrium studies and a 13 C NMR spectroscopic analysis.

TL;DR: The enclathration of 2-propanol (2-PrOH) as a co-guest of structure II (sII) hydrates in the presence of CH4 and CO2 was experimentally verified with a focus on macroscopic phase behaviors and microscopic analytical methods such as powder X-ray diffraction (PXRD) and NMR spectroscopy.
