We investigated the Ni/ZrO2 catalyst performance of YBa2Cu3O7-x (YBCO) membrane reactor in the process of partial oxidation of methane (POM) to syngas by TG. The activity of the catalyst effected not only on the methane conversion but also CO selectivity. The effect of temperature on CO selectivity was little and could be neglected.The change of CH4 conversion along time was caused by the deactivation of catalyst or/and the decay of membrane reactor. The loss of catalysts increase with temperature accoding to the carves of TG .

Cerium doping into the V2O5 lattice forms a reversible V2O3/VO redox pair after sequential methane partial oxidation and CO2/H2O splitting reactions and produces syngas (H2, CO) with fast rates and high oxygen exchange capacity.

The performance of Ni/SiO2 Catalysts modified by La2O3, ZrO2 and CeO2 were tested in a BaCo0.7Fe0.2Nb0.1O3-δ (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/RxOy/SiO2 (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/cm2•min and a CH4 conversion of 99.2% have been achieved at 900 oC.
