Resumen:
The combination of CO2 reforming and oxidation of methane is currently being studied in conventional
reactors trying to improve the energy balance in the production of synthesis gas. In this work, we applied
the same concept to membrane reactors used to produce pureH2. Two catalysts were used, Rh(0.6)/La2O3

2 reforming and oxidation of methane is currently being studied in conventional
reactors trying to improve the energy balance in the production of synthesis gas. In this work, we applied
the same concept to membrane reactors used to produce pureH2. Two catalysts were used, Rh(0.6)/La2O32. Two catalysts were used, Rh(0.6)/La2O3
and Rh(0.6)/La2O3(27)SiO2. They were first assayed in a conventional fixed-bed reactor (CR) in order
to test their activity and stability before being used in the membrane reactor (MR). The latter was especially
designed to detect the presence of hot spots in the catalyst bed and avoid the contact of O2 rich
atmospheres at high temperature (823 K) with the PdAg membrane. Varying O2 contents (010%) and
CO2/CH4 ratios between 0.5 and 1.9 were fed to the membrane reactor to quantify their effect upon
methane conversion and H2 production and recovery through the membrane. The fresh, reduced and
used catalysts were characterized through XRD, laser Raman spectroscopy and XPS. The spectroscopic
features were consistent with the catalytic behavior of both formulations. The best performance of the
MR was achieved using Rh supported on the binary oxide, 10% O2 and CO2/CH4 = 1.9.
