英文摘要: A new Ni-BaCe0.6Zr0.2Nd0.2O3-delta(Ni-BZCN6) cermet membrane was investigated to separate hydrogen from hydrogen-containing mixtures. Hydrogen permeation properties of the membrane and permeation stability under atmospheres containing CO2 and H2O were investigated tinder different conditions. Hydrogen permeation flux increases with increasing temperature. When the feed gas was moistened by 3% H2O, the flux was about 2-5 times that not moistened. It reached 0.073 cm(3)/(min cm(2)) at 900 degrees C when a wet feed gas of 80% H-2/He was used. After 100 h operation tinder 30% CO2, the membrane still keeps a steady permeation flux. These results suggest that the Ni-BZCN6 membrane is suitable for hydrogen separation from mixed gas containing H-2 and CO2.
