摘要：
The performance of Ni/SiO(2) Catalysts modified by La(2)O(3), ZrO(2) and CeO(2) were tested in a BaCo(0.7)Fe(0.2)Nb(0.1)O(3-delta) (BCFNO) membrane reactor by catalytic partial oxidation of coke oven gas (COG) under atmospheric pressure. The results show that the oxygen permeation flux increased dramatically with Ni/R(x)O(y)/SiO(2) (R = La, Zr or Ce) catalysts by adding the element of rare earth especially the La during the reforming reaction. At optimized reaction conditions, the dense oxygen permeable membrane had an oxygen permeation flux around 16.4 ml/cm(2).min and a CH(4) conversion of 99.2% have been achieved at 900 degrees C.
