Various thin-film supported membranes have been prepared by simultaneous Pd-Ag electroless plating and have been initially sealed with a sealing procedure previously validated for Water gas shift (WGS) application (400 °C). The membranes have been characterized for single gas and mixed gas permeation, and for methane steam and autothermal reforming in a fluidized bed membrane reactor at 550-600 °C using a Ru-based catalyst. In addition, the performance of these membranes was compared to commercial membranes from REB Research & Consulting under the same reaction conditions. The applied sealing showed nitrogen leaks at 600 °C and different sealing approaches were tested solving this problem. Finally, also the long-term stability of the thin-film Pd-Ag supported membrane at 600 °C has been investigated.16enginfo:eu-repo/semantics/openAccessjournal article10.1016/j.ijhydene.2015.08.050Autothermal steam reformingFluidized bed membrane reactorHigh temperature sealingMembrane stabilityPalladium membrane preparationCondensed Matter PhysicsEnergy Engineering and Power TechnologyFuel TechnologyRenewable Energy, Sustainability and the EnvironmentSDG 7 - Affordable and Clean Energyhttp://www.scopus.com/inward/record.url?scp=84944160984&partnerID=8YFLogxK
