A novel Pd–Cu–Zr hydrogen separation membrane with a high tolerance to sulphur poisoning†
Abstract
The effects of the addition of small amount of Zr (less than 2 at%) to the fcc phase of the Pd–Cu hydrogen separation alloy were investigated. Hydrogen flux variations in Pd–Cu and Pd–Cu–Zr alloys in the presence of 1000 ppm H2S + H2 feed gas showed a marked effect of Zr addition in improving the resistance to sulphur poisoning.
