The effect of CO on hydrogen permeation through Pd and through internally oxidized and un-oxidized Pd alloy membranes
Pd alloy permeation membranes such as Pd-Al and Pd-Fe which have been internally oxidized are more resistant to inhibition by CO(g) than Pd or un-oxidized alloy membranes. The increased resistance to CO is found to be greater at 423 K than at 473 K or 523 K. In these experiments CO was pre-adsorbed onto the membranes and then H(2) was introduced to initiate the H permeation. (C) 2011 Elsevier B.V. All rights reserved.
