Conversion of ammonia to hydrogen and nitrogen using ammonia as a sweep gas

Abstract

The disclosure relates to systems and methods for the production of hydrogen (H2) from ammonia (NH3) in a membrane reactor that include using ammonia as a sweep gas. Ammonia is converted to hydrogen and nitrogen (N2), and the hydrogen is separated from the nitrogen and unreacted ammonia by passing the hydrogen through a hydrogen-permeable membrane while using ammonia as a sweep gas. The ammonia sweep gas can be separated from the permeated hydrogen and continuously recycled.

Dependencies are inferred from the claim text.
