Method and system for obtaining a hydrogen-containing product using ammonia

Abstract

The invention relates to a method and a system (100) for producing a hydrogen-containing product, wherein ammonia (2) is reacted in an ammonia cracker (20) to which heat is supplied, wherein the ammonia cracker (20) has a catalyst bed with at least two catalyst segments (20a, 20b, 20c), wherein in a first catalyst segment (20a) a fraction of the ammonia (2) is reacted at a first minimum temperature (T1) using a first catalyst and in a second catalyst segment (20b), which is downstream of the first catalyst segment (20a), a further fraction of the ammonia (2) is reacted at a second minimum temperature (T2) using a second catalyst. The invention is characterised in that the first minimum temperature (T1) is lower than the second minimum temperature (T2).
