In this paper we found two catalysts exhibit high catalytic activity and stability during the partial oxidation of methane (POM) in Coke oven gas (COG) in BCFNO membrane reactor. Such as the NiO/MgO catalyst, we discussed the COG and air flow rate on the performance of reforming of COG. The results show that the NiO/MgO catalyst exhibits high activity. The experimental result of the CH4 conversion, selectivity of H2 and CO were suited well to the result of thermodynamic analysis. And the LiNiCeO/γ-Al2O3 catalyst, we discussed the LiNiCeO/γ-Al2O3 catalysts with different amount CeO2 in order to compare the reaction performance on the membrane reactor. The results show that the oxygen permeation flux increased significantly with increasing the amount of CeO2 during the POM in COG. Such as, the LiNi15%CeO/γ-Al2O3 catalyst with a oxygen permeation flux of 10.6 ml⋅cm-2⋅min-1 and a 100% CH4 conversion were obtained at 875 oC.
