Applications of oxygen gas separation membranes

Application Oxyfuel three end Oxyfuel four end Syngas [Pg.708]

Membranes based on acceptor-doped ceria may represent a promising alternative to Ln,Tm-based perovskites. Ceria has a much wider pOg stability range and a higher ionic conductivity than most of the Tm-based perovskites at 700 °C the ionic conductivity of Ceo.gGdo.iOi 95 is 0.04 while the ionic conductivity of [Pg.708]

4 Enhancing electronic conductivity in ceria-based membranes [Pg.712]

As pointed out above, the performance-limiting factor of a Gcj. Gdy02—y/2 membrane is electronic conductivity. Different ways of enhancing electronic conductivity in acceptor-doped ceria have [Pg.712]

Recorded membrane performances of a range of different materials systems ceria are summarized in Table 12.6. The materials have been grouped into four classes (i) composite membranes, (ii) materials with redox active dopants, (iii) acceptor-doped materials, and (iv) materials with additional co-substitution. Selected results are either discussed above (Sections 12.6.4.2 and 12.6.4.3) or in the following sections and in Section 12.6.4.5. [Pg.713]
