This agrees with very low CO 2 conversions and represents the worst scenario for the desired process of carbon dioxide methanation, giving very low reaction of carbon dioxide and no yield to methane. When higher CO 2 conversions are reached (in this case by increasing temperature for a given W/F CO2 ratio), the selectivity to CO decreases as ...
