| 英文摘要 | Membrane thickness and structural type, which are closely related to the species diffusion in the membrane bulk and reactions at the gas-solid interfaces, have important influences on the performance of a dense ceramic membrane. recently, oxygen-permeable dense ceramic membrane reactors have been suggested for hydrogen purification at elevated temperatures. mixed conducting composite with composition of 75 wt% ce0.85sm0.15o2-delta-25 wt% sm0.6sr0.4al0.3fe0.7o3-delta (sdc-ssaf) was fabricated into oxygen-permeable membranes with different thicknesses and structural types. the effects of membrane thickness and structural type on the hydrogen separation performance were tested under different hydrogen concentrations and flow rates on side i, different flow rates of steam/he mixed gas on side ii as well as different temperatures. the effect of concentration polarization on hydrogen separation rate and the rate determining steps were discussed by comparing the performances of the symmetric membranes and the asymmetric membranes. the apparent activation energies of the membrane reactors for hydrogen separation were analyzed. this study will give some constructive guides to the subsequent work on how to effectively improve the hydrogen separation performance. |
