abstract = {The equilibrium limitations of water splitting and the
coupling of methane to C-2 hydrocarbons (ethane + ethylene)
were simultaneously overcome by using a perovskite
Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF) oxygen-permeable
membrane reactor. Oxygen produced from thermal water
splitting was transported through the BSCF membrane and
consumed in the coupling of methane. The BSCF membrane
consists of an about 70 mu m thick dense BSCF layer on an
about 0.8 mm thick porous BSCF layer as support. By applying
the membrane reactor concept instead of a fixed bed reactor
without oxygen supply, the methane conversion and C-2 yield
increased from $3.7\%$ to $26\%$ and $3.1\%$ to $6.5\%$ at
950 degrees C, respectively. In both experiments, the
supported 2 $wt.\%$ Mn-5 $wt.\%$ Na2WO4 catalyst was used at
950 degrees C. Simultaneously, about $9\%$ of the H2O
injected was converted to hydrogen with a production rate of
about 3.3 cm(3) min(-1) cm(-2) at 950 degrees C which is
higher than 1 m(3) (STP) H-2 m(-2)h(-1). (c) 2011 Elsevier
