limiting reactant (CO

) will be consumed, with a substantial fraction of methane still
remaining unconverted.
Carbon accumulation over the catalyst, originating from CO disproportionation
into carbon and carbon dioxide (Equation 5.6) can also be prominent [20], especially
at temperatures below 700°C, where the equilibrium of this reaction is favored.
Consequently, the operating reaction temperature for methane dry reforming reac-
tion should be high enough (above 700°C) in order to minimize the negative con-
tribution of this reaction [16]. In Figure 5.3, the amount of accumulated ...
