  • Method for preparing a palladium-gold alloy gas separation membrane system
    Patent number: 8721773
    Abstract: A method for preparing a palladium-gold alloy gas separation membrane system comprising a gold-palladium alloy membrane on a porous substrate coated with an intermetallic diffusion barrier. The method includes an abrading step to increase surface roughness of the palladium to a desired range, a gold plating step with a solution of chloroauric acid (AuCl4H) and hydrogen peroxide, followed by annealing to produce a palladium-gold alloy membrane.
    Type: Grant
    Filed: October 26, 2011
    Date of Patent: May 13, 2014
    Assignee: Shell Oil Company
    Inventors: Nathan Earl Perkins, II, John Charles Saukaitis
