Abstract

In this paper, a model has been proposed for HYDROGEN permeation through PALLADIUM/alumina NANOCOMPOSITE MEMBRANES. With regards to H2 /N2 binary gas mixture as feed and also thickness of the PALLADIUM nanocomposite layer, among different six stages of HYDROGEN transport through membrane, three stages; desorption of H2 from PALLADIUM surface, diffusion of H2 through metal layer and H2 transport through ceramic porous layer because of their effectiveness in total HYDROGEN permeation, were considered in the proposed model and their mechanisms were studied with more details. Adjustable variables of model which are effective on HYDROGEN permeation were determined based on the literature experimental and theoretical works. Finally, a general model for HYDROGEN flux through PALLADIUM/alumina NANOCOMPOSITE MEMBRANES was proposed by considering the resistance of each stage. The proposed model was verified by comparing the model results with literature which were in a good agreement. The obtained results illustrated that at higher temperatures, diffusion through PALLADIUM metal layer and at lower temperatures, desorption of HYDROGEN atoms from PALLADIUM surface are controlling stages for HYDROGEN transport through PALLADIUM NANOCOMPOSITE MEMBRANES.
