“temperature is the most important parameter in methanation process, and should be well controlled in the iCCC-Methane to make the CO2 capture and methanation conversion matched. Bermejo-López et al. [45] explored the influence of the temperature on iCCC-Methane, and found the temperature showed a positive correlation with CH4 yield. Both CO2 adsorption and methanation are exothermic processes and thus are thermodynamically favored at low temperatures, while reaction kinetics follow the opposite trend. A similar influence of temperature on iCCC-Methane was also observed by González-Velasco et al. [46]. Through serials of controlled experiments, Zheng et al. [47] found that the optimum methanation rate occurred at around 320 °C. “
