      abstract     = {Synthesis gas with a CO/H2 ratio suitable for production of
                      energy carriers, e.g. hydrogen, methanol, and gasoline, can
                      be produced by gasification of solid fuels with subsequent
                      water-gas-shift (WGS) reaction. The separation of CO2 using
                      conventional absorption processes leads to high efficiency
                      losses. In contrast, a membrane reactor containing a
                      catalyst provides the opportunity for significantly reduced
                      efficiency losses.The present work aims at developing a
                      chemically stable membrane for separation of carbon dioxide
                      in gasification atmosphere. The desired membrane consists of
                      two phases, a porous ceramic oxygen ion conductor filled
                      with molten carbonate. Both phases need to be stable under
                      the relevant process conditions, i.e. syngas at up to
                      800 °C, and compatible with each other and the water gas
                      shift catalyst. The potential oxygen ion conductor
                      materials, e.g. cerium gadolinium oxide (Ce0.8Gd0.2O2-δ)
                      and cerium samarium oxide (Ce0.8Sm0.2O2-δ), which are known
                      from literature to be compatible with alkali carbonate
                      melts, were exposed to different gasification-relevant gas
                      atmospheres at 600–900 °C and subsequently investigated
                      regarding chemical reactions. Furthermore thermodynamic
                      properties of alkali and alkaline earth carbonate systems
                      were studied to identify a mixture with suitable melting
                      behavior and high chemical stability as well as low
                      volatility under relevant syngas conditions.},
