Methanation process

Methanation is a chemical reaction that converts carbon monoxide and/or carbon dioxide to methane. The production of methane across the "Sabatier" reaction (1) is a well-known process for converting CO 2 to a useful product and was proposed by Paul Sabatier and J.B. Sendersens in 1902. A large-scale production of methane on the basis of carbon dioxide has never been …
