Hydration of Gases to Reduce Major Greenhouse Gases Emission into the Atmosphere

A technology on replacement methane (CH₄) from natural gas hydrate (NGH) with carbon dioxide (CO₂) is described. And the technology is demonstrated in theoretics and experiment, respectively. Moreover, combined with the main emission channel of CH₄ in coal industry, the reducing emission technology of coalbed methane(CBM) based on hydration is narrated. The formation and dissociation technique of CH₄ hydrates are elaborated. The process of hydrate formation of CBM with different methane concentrations is investigated using self-developed experiment apparatus. The results show that the CBM hydrates are prone to be formed under appropriate conditions. The analysis of the experimental data and results in the former literature indicates that the reducing emission of greenhouse gases (GHGs) such as CO₂ and CH₄ on hydrate technology is feasible.
