Methane steam reforming (MSR) over a Rh-loaded Ce<SUB>0.15</SUB>Zr<SUB>0.85</SUB>O<SUB>2</SUB> catalyst in a membrane reactor was investigated. An yttria-stabilized zirconia (YSZ) membrane used in the membrane reactor showed an ideal H<SUB>2</SUB>/N<SUB>2</SUB> selectivity of 6.6 at a H<SUB>2</SUB> permeance of 3.3 × 10<SUP>–6</SUP> mol m<SUP>–2</SUP> s<SUP>–1</SUP> Pa<SUP>–1</SUP> at 500°C. Methane conversions in the membrane reactor were higher than those in a packed bed reactor due to the sufficient permeation rate of hydrogen, which shifted the equilibrium, reaching 82% at 550°C. To evaluate the stability of a membrane reactor, the methane conversion was measured as a function of time. As a result, no significant change in methane conversion was evident at 500°C for 7 h.
