Methanation-technology
Methanation technology
Methanation refers to the production of methane by the equilibrium reaction of carbon monoxide and hydrogen.
This highly exothermic reaction is the reverse process of steam methane reforming.
Johnson Matthey's DAVY™ methanation technology forms the core of our substitute natural gas (SNG) process, which converts gasified coal into high methane-content fuel gas.
Our methanation technology, utilising our CRG catalysts , performs the key chemical transformation of syngas into SNG, and ensures the final product is of a suitable quality for injection into gas distribution networks.
The CRG catalyst facilitates the methanation reaction and also a simultaneous CO shift reaction.
The CO shift reaction consumes excess CO2 and increases the CO content of the gas, which is necessary for methanation.
