“…All this was assembled inside a Pyrex tube (in the shell) in a fingerlike configuration accordingly to a well-established and proven membrane module design [19]. One end of the permeator tube is sealed while the other one allows the placing of a stainless steel channel which is responsible for supplying the feed gas mixture.…”

The permeability of a 0.175 mm thick Pd-Ag tubular membrane to pure H2 and binary mixtures of H2/CO or H2/CO2 was studied. The tests were performed in a wide range of temperature (523-723 K) and pressure (200-800 kPa).Pure H2-permeation through a dense metal membrane is described by the Sieverts' law. However, it was already found that the H2 permeation does not follow the Sieverts' law when other components are present in the feed and namely CO or CO2. In this work, it is proposed a new permeation model based on the Sieverts' law considering: i) the mass transfer resistance due to the surface effects and ii) the barrier effect due to the presence of either CO or CO2. The model was successfully validated against experimental data of hydrogen permeation for binary (H2/CO and H2/CO2) experiments for every working temperature and pressure.

“…The use of this "finger-like" configuration allows the free elongation and contraction of the membrane, thus avoiding any mechanical stress that may damage the thin wall tube. Besides, this kind of membranes allows obtaining ultrapure hydrogen due to their nearly infinite permselectivity towards H 2 [7,8]. However, for the implementation of these membranes in hydrogen production/ purification applications, it is crucial to measure permeability under different conditions (partial pressures and temperatures).…”
