Abstract

Methane steam reforming (MSR) over a Rh-loaded Ce_0.15Zr_0.85O₂ catalyst in a membrane reactor was investigated. An yttria-stabilized zirconia (YSZ) membrane used in the membrane reactor showed an ideal H₂/N₂ selectivity of 6.6 at a H₂ permeance of 3.3 × 10^–6 mol m^–2 s^–1 Pa^–1 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.
