Abstract

The La₂NiO₄-zeolite membrane was prepared by means of in situ hydrothermal synthesis. Techniques such as XRD, SEM-EDX, and BET were used to acquire information as related to the structure, morphology and the pore size distribution of the membrane. At room temperature, we observed a H₂/CH₄ separation factor of 9.2, considerably higher than the Knudsen diffusion value. With the simultaneous separation of CO and H₂ in the membrane reactor, both CO₂ and CH₄ conversions were enhanced in the CH₄/CO₂ reforming reaction.
