However, the long-term performance and stability of the applied membranes are extremely important for the possible industrial exploitation of these reactors. This study investigates the long-term stability of thin-film Pd-Ag membranes supported on porous Al2O3 supports. The stability of five similarly prepared membranes have been investigated for 2650 h, up to 600 °C and in fluidized bed conditions. Results show the importance and the contribution of the sealing of the membranes at temperatures up to 500 °C. At higher temperatures the membranes surface deformation results in pinhole formation and a consequent decrease in selectivity. Stable operation of the membranes in a fluidized bed is observed up to 450 °C, however, at higher temperatures the scouring action of the particles under fluidization causes significant deformation of the palladium surface resulting in a decreased selectivity.111887049enginfo:eu-repo/semantics/openAccessjournal article10.3390/pr7020106Palladium based membranesMembrane stabilityMembrane reactorsFluidized bedHydrogen productionPalladium based membranesMembrane stabilityMembrane reactorsFluidized bedHydrogen productionBioengineeringChemical Engineering (miscellaneous)Process Chemistry and TechnologyProject IDinfo:eu-repo/grantAgreement/EC/H2020/671459/EU/BIOgas membrane reformer for deceNtralIzed hydrogen produCtiOn/BIONICOinfo:eu-repo/grantAgreement/EC/H2020/671459/EU/BIOgas membrane reformer for deceNtralIzed hydrogen produCtiOn/BIONICOFunding InfoThe presented work is funded within BIONICO.
