METH® 134 Sabatier Methanization
METH® 134 is a nickel catalyst and catalyzes the methanation of CO2 (Sabatier reaction: CO2 + 4 H2 -> CH4 + 2 H2O) and CO.
Methanation is a chemical reaction in which carbon oxides (such as carbon monoxide, CO, and carbon dioxide, CO2) react with hydrogen to form methane (CH4). The generalized chemical equation for methanation is:
CO + 3H2 → CH4 + H2O
One method for CO reduction involves the use of water-gas shift reactions, which convert carbon monoxide and water into carbon dioxide and hydrogen:
CO+H2O→CO2+H2.
In industrial environments, various technologies and catalysts can be used to increase the efficiency of reforming processes and reduce environmental impact by minimizing carbon monoxide emissions.
METH® 134 is a highly active methanation catalyst. This alumina-based nickel catalyst operates above 200 °C and is well-suited for standard methanation applications in ammonia synthesis or synthesis gas production. Other specialty catalysts are available.
On an industrial scale, after primary and secondary reforming for the production of synthesis gas for ammonia plants, the Meth® 134 methanation catalyst is used in the H2-N2 feed gas purification process following low-temperature shift (LTS) and CO2 capture to remove residual CO through methanation. This protects the ammonia synthesis catalyst.
Another application area for the nickel-based methanation catalyst Meth® 134 lies in the Power-to-X sector. Due to current efforts to chemically store renewable hydrogen produced by electrolysis (“green hydrogen”) using surplus electricity from wind turbines, the methanation process, investigated as early as 1902 by the French chemist Paul Sabatier, via the catalytic hydrogenation of CO2 (CO2 + 3 H2 CH4 + 2 H2O, H: -165.0 kJ/mol), is gaining increasing importance for the production of substitute natural gas (SNG). In this process, the methanation reactor must be designed in such a way that the high heat of reaction generated can be dissipated through effective cooling.
