Process for separating hydrogen from gas mixtures using a semi-permeable membrane consisting predominantly of polycarbonates derived from tetrahalobisphenols


, : Process for separating hydrogen from gas mixtures using a semi-permeable membrane consisting predominantly of polycarbonates derived from tetrahalobisphenols. United States Patent (US 5,000,763): 8 pp.

Membrane separation of hydrogen from gas mixtures containing nitrogen, CO, CO2, and/or light hydrocarbons is of particular interest. The title membranes demonstrate high separation factors and high permeability for the separation of hydrogen from gas mixtures.
