WebJul 6, 2013 · During the Sabatier reaction, the volume of the gas stream is reduced. If a conversion of 100 % is assumed, the gas volume would be reduced by a factor of five (only CH 4, H 2 O is removed by the cooling trap). The optimal CO 2 -methanation reaction performance at 350 °C is also confirmed by the output flow here. WebNov 12, 2024 · To this end, hydrogen represents chemical storage for renewable electricity when it is produced by water electrolysis, and it is also the key reactant for CO 2 methanation (Sabatier reaction). In this latter case, the produced methane is a carbon-neutral gas that fits into existing infrastructure [ 1 ].
