摘要：

The water-gas shift (WGS) reaction is used to shift the CO/H-2 ratio prior to Fischer-Tropsch synthesis and/or to increase H-2 yield. A WGS membrane reactor was developed using a mixed protonic-electronic conducting SrCe0.9Eu0.1O3-delta membrane coated on a Ni-SrCeO3-delta support. The membrane reactor overcomes the thermodynamic equilibrium limitations. A 46% increase in CO conversion and total H-2 yield was achieved at 900 degrees C under 3% CO and 6% H2O, resulting in a 92% single pass H-2 production yield and 32% single pass yield of pure permeated H-2.
