Due to its importance to produce fertilizers and its widely discussed potential as carrier molecule for green hydrogen (H2) or marine fuel, the production of ammonia (NH3) is projected to increase from 185 Mt/a in 2020 to up to 500 Mt/a in 2050 . This increasing production capacity strengthens the need for efficient process concepts, which leads to extensive research into different process intensification approaches for the NH3 synthesis . Next to more unconventional process intensification approaches, such as electrochemical or plasma-based synthesis approaches , intensification through in situ removal of NH3 in the commercially applied thermochemical NH3 synthesis is extensively investigated in literature . In general, the in situ separation is defined as the selective removal of a product or by-product of a chemical reaction within the reaction volume. For heterogeneously catalyzed reactions, the spatial combination of the separation and the reaction within a single bifunctional reactor is of special interest .
