Palladium-based composite membranes for hydrogen separation in membrane reactors

PINACCI, Research on the Energetic System (RSE) S.p.A Italy and A. BASILE, ITM-CNR, Italy [Pg.149]

Key words palladinm composite membranes, electroless plating, magnetron spnttering, hydrogen separation. [Pg.149]

Membrane 0PO.B (nm) Diffusion mechanism H2/other gas permeance Reactant loss [Pg.150]

Macroporous 50 Poiseuille (viscous flow) 1 Very high High [Pg.150]

These thinner composite membranes offer several clear advantages over the thick-walled palladium-based ones including higher hydrogen fluxes, very high Hj selectivity and reduced palladium costs. [Pg.151]
