reactants. The mole fractions of important gaseous products
as functions of reaction temperature, at a CH4/flue gas ratio
equal to 0.4 and a pressure of 1 atm can be seen in Fig. 4. At the
lowest temperature (400 C), the mole fraction of CO begins to
increase from zero and reaches a maximum 850 C. At the
same time, the mole fraction of CO2 decreases to zero when
the temperature was 850 C, indicating that CO2 serves as a
limiting reactant in the reactions. From the reactions of the
tri-reforming process (R1eR9), it is known that the consumption
of CH4 is the main source for the production of H2.
As the temperature increases, H2 mole fraction keeps
increasing while CH4 mole fraction keeps decreasing, verifying
that there is a parallel relationship between CH4 consumption
and H2 production
