CO<sub>2</sub> hydrate formation and dissociation is crucial for hydrate-based CO<sub>2 </sub>capture and storage. Experimental and calculated phase equilibrium conditions of carbon dioxide (CO<sub>2</sub>) hydrate in porous medium were investigated in this study. Glass beads were used to form the porous medium. The...

This paper introduces the research advances on replacement of CH<sub>4</sub> in Natural Gas Hydrates (NGHs) by use of CO<sub>2</sub> and discusses the advantages and disadvantages of the method on the natural gas production from such hydrates. Firstly, the feasibility of replacement is proven from the points of view...
