3.2. Syngas production
Fig. 4 shows the flow rate distributions of H2, CO, and syngas at
the exit of the reactor with respect to the CO2/O2 ratio at O/C = 1.
The flow rate of H2 is reduced with increasing the ratio, as a
consequence of the abatement of methane combustion and steam
reforming. Contrary to H2 formation, the flow rate of CO is raised
when CO2 is added into the influent. Once the addition of CO2 is
large to a certain extent, the flow rate of CO is lowered. The
maximum flow rate of CO is 1.22 mol h1 which occurs at CO2/
O2 = 1.4. When the formation of H2 and CO is simultaneously
considered, the maximum flow rate of syngas is 2.74 mol h1
which develops at CO2/O2 = 0.2.
