Assessment of Sieverts Law Assumptions and 'n' Values in Palladium Membranes: Experimental and Theoretical Analyses.

ABSTRACT: Palladium and palladium alloy membranes are superior materials for hydrogen purification, removal, or reaction processes. Sieverts' Law suggests that the flux of hydrogen through such membranes is proportional to the difference between the feed and permeate side partial pressures, each raised to the 0.5 power (n = 0.5). Sieverts' Law is widely applied in analyzing the steady state hydrogen permeation through Pd-based membranes, even in some cases where the assumptions made in deriving Sieverts' Law do not apply. Often permeation data are fit to the model allowing the pressure exponent (n) to vary. This study experimentally assessed the validity of Sieverts' Law as hydrogen was separated from other gases and theoretically modelled the effects of pressure and temperature on the assumptions a
