Green ammonia synthesis from stationary NOx emission sources on a catalytic lean NOx trap

Abstract

A process for producing ammonia out of NOx from hydrogen engine flue gases is proposed. NOx is captured on a lean NOx trap (LNT) and catalytically reduced with hydrogen to ammonia (NOCCRA). The energy requirement is similar to that of Haber-Bosch processes. NOCCRA is attractive for decentralised green NH3 production.
