Catalytic partial oxidation of methane to synthesis gas over Ni/γ-Al2O3 catalyst in a fluidized-bed Original Research Article

The catalytic partial oxidation of methane to synthesis gas over Ni/γ-Al2O3 catalyst has been investigated in a fluidized-bed reactor. The results showed that an isothermal operation and the performance near to thermodynamic equilibrium could be obtained in a fluidized-bed reactor. A study on carbon deposit showed that there was a low rate of carbon formation in a fluidized-bed reactor. The CH4 conversion as well as CO and H2 selectivities remained constant at ∼92, ∼94 and ∼99.0%, respectively, during 100 h running. Neither phase transformation of the support nor remarkable Ni loss was found on the catalyst after 100 h running.
