Abstract:

An input stream of gaseous nitrogen and carbon dioxide is introduced into a first interior volume of a separation vessel that is divided into first and second interior volumes by a separation membrane that includes a metal layer. The metal layer selectively permits movement of nitrogen through the metal layer. An output stream of gaseous nitrogen and carbon dioxide is conveyed out of the first interior volume and into a reaction vessel. The volume fraction of carbon dioxide is greater in the output stream than in the input stream; the volume fraction of nitrogen is reduced in the output stream relative to the input stream. Nitrogen is removed from the second interior volume to maintain a gradient of nitrogen partial pressure across the separation membrane that causes net transport of nitrogen from the first interior volume through the separation membrane into the second interior volume.

Abstract:

The invention relates to a metallic membrane for nitrogen separation, the method of making the membrane and methods of using the membrane. The invention also relates to a metallic membrane for disassociation of nitrogen and subsequent reaction with hydrogen to produce ammonia at moderate conditions compared to a conventional Haber-Bosch process.
