CO2 is one of the most important greenhouse gases and it has a huge impact on exacerbating this phenomenon. Therefore, its removal from flue gas and natural gas has always been one of the most important issues for the industry. One of the ways that has received much attention recently is to trap and store it in the gas clathrate hydrate. Both thermodynamic hydrate formation conditions and kinetics of CO2 hydrate have been investigated by researches to reduce equilibrium pressure and increase temperature, and particularly, promote kinetically hydrate formation. In this work, we used cyclopentane as a thermodynamic promoter and silica nanoparticles as a kinetics promoter to address these two shortcomings in gas hydrate formation. The present results show well that both thermodynamic and kinetic promoters are very useful in facilitating the formation of carbon dioxide gas hydrates. We conducted our experiments with two different concentrations of cyclopentane and silica nanoparticles.
