The partial oxidation of methane to synthesis gas (POX) over N1/AI2O3 catalysts has been studied in a fluidized bed reactor. Flow characterization studies showed that the reaction zone was isothermal, and that the back mixing of gas was negligible. The reaction was rapid, and full O2 conversion was achieved after 8 ms contact time over 1.5%Ni/Al2O3at 700°C, with CH4/O2/N2/H2O =2/1/2/0.5. The CO selectivity went through a minimum and then increased and approached equilibrium after 48 ms contact time. Simulations of the reaction scheme indicated that the catalyst is active for oxidation of CH4, CO and H2, as well as for reforming. The simulations further suggested that the reaction rates were diffusion limited.
