Abstract
A process and a reactor system for producing ammonia is described. The ammonia produced, such as by the Haber process, is absorbed into an ionic liquid. The removal of ammonia shifts the reaction equilibrium toward the production of ammonia, resulting in higher yields of ammonia.
Claims12
A process for producing ammonia comprising the steps of:
- (a) combining nitrogen and hydrogen in the presence of a catalyst to produce ammonia;
- and
- (b) absorbing a portion of the ammonia so produced with an ionic liquid that comprises an ammonium cation.
