Abstract

Embodiments of the disclosure provide an apparatus and process for producing ammonia. The apparatus includes a reactor having (i) an inlet to receive an inlet gas comprising nitrogen and hydrogen, (ii) a catalyst and an absorbent disposed within an internal volume of the reactor, the catalyst configured to convert the nitrogen and hydrogen to a reaction mixture including ammonia, unreacted nitrogen, and unreacted hydrogen, the absorbent configured to selectively absorb a portion of the ammonia in the reactor during formation of the reaction mixture, and (iii) an outlet to discharge the reaction mixture from the reactor.
