Methane dry reforming is a promising approach for hydrogen production due to the simultaneous utilization of two greenhouse gases, methane and carbon dioxide. The implementation of methane dry reforming in catalytic reactors that utilize hydrogen separation membranes was demonstrated to enhance the process efficiency. This enhancement is attributed to the elimination of hydrogen, a product of the reaction, through the use of these membranes. The materials based on La1−xCaxNbO4±δ demonstrate considerable promise in applications involving hydrogen separation membranes due to their high protonic conductivity and stability under operational conditions. In this study, an asymmetric foam-supported membrane was fabricated and characterized in a hydrogen permeation test and a methane dry reforming reaction. The membrane is composed of a NiAl foam support, a La0.99Ca0.01NbO4±δ–NiCoOx dense permselective layer, and a NiRu/Pr0.3Ce0.35Zr0.35O2−δ catalytic layer. The membrane displays a high hydrogen permeation flux of ~2.5 ml H2/(cm2 min) at 700 °C in permeation tests and ~1.4 ml H2/(cm2 min) at 700 °C in methane dry reforming tests. Such a high hydrogen permeability can be attributed to the high protonic mobility of the permselective composite layer, as well as coupled electron and oxide ion transport. The conversion of methane and carbon dioxide is ~60% and ~80%, respectively. However, the membrane performance is demonstrated to slowly decline over a period of 100 hours of time-on-stream, which indicates that the composite and the catalyst materials require further development for more efficient application in catalytic membrane reactors for hydrogen production via methane dry reforming.
