Sauerstofftransport und Degradationsverhalten von Hochtemperaturmembranen für CO 2-freie Kraftwerke
This thesis deals with membranes for oxygen separation from air for high temperature application in fossil power plants within the scope of the oxyfuel-process. Different perovskite membrane materials (ABO3-d) were investigated concerning the oxygen transport and their chemical stability under …

Oxygen transport in Ba(Fe,Co,Zr)O 3 - delta membranes
The nonstoichiometry of Ba(Fe,Co,Zr)O3-delta (Zr-lean Ba(Fe,Co,Zr)O3-delta) is measured as a function of temperature and oxygen activity by TG. Very high nonstoichiometry (delta0=0.78 at a(O2)=1) is determined at 1273 K. From the nonstoichiometry of Ba(Fe,Co,Zr)O3-delta;, exponent n (n=-0.01) in …
