A process for recycling and reusing supported Pd membranes includes the separation of the Pd (or Pd alloy) layer from the support by contacting the Pd membrane with hydrogen under pressure and at low temperature and then with a second gas that is different from hydrogen. The Pd layer separated from the support can then be treated to solubilize the Pd and, where appropriate, the alloy metal(s) to obtain salts that can be reused, for example in the preparation of new Pd membranes. The recovered supports are also reusable.

A method for low hydrogen content separation from a natural gas mixture includes the following steps: a) providing a stream having hydrogen; b) transferring the stream having hydrogen of a) as an inlet stream to a first membrane unit for obtaining a retentate and a permeate, wherein the molar fraction of hydrogen in the permeate is higher that the molar fraction of hydrogen in the retentate, c) transferring the retentate to an electrochemical hydrogen compressor (EHC) for further hydrogen separation and purification.
