On the other hand, as the reaction temperature goes beyond 850 C,
CO2 content reaches zero for the CH4/Flue Gas ratio ranging
from 0.4 to 1.0, suggesting that CO2 is the limiting reactant in
the tri-reforming process which restricts further production of
H2 and CO. In this sense, the CH4/Flue gas ratio is selected to be
1.0 to maximize CO and H2 production.
