Abstract
A process for separating hydrogen from a multicomponent gas mixture containing hydrogen and a hydrocarbon, using gas-separation membranes selective for hydrogen over the hydrocarbon. The membranes use a selective layer made from a polymer having repeating units of a fluorinated polymer, and demonstrate good resistance to plasticization by the organic components in the gas mixture under treatment, and good recovery after exposure to liquid aromatic hydrocarbons.
