Abstract

Apparatus for producing hydrogen from a cracking reaction of ammonia, said apparatus comprising:- a cracker unit (1) configured for producing a cracked gas from ammonia,- an absorber (2) configured for removing unconverted ammonia from said cracked gas using an absorbent fluid, thereby producing an ammonia depleted gas containing hydrogen, nitrogen and vaporized absorbent fluid,- an adsorption unit (3) comprising at least one adsorber vessel (4), said adsorber vessel or each adsorber vessel comprising a feed end arranged for receiving said ammonia depleted gas, a product end downstream said feed end for discharging a purified hydrogen product from said adsorber vessel, and an adsorbent bed arranged between said feed end and said product end, the adsorbent bed comprising an upstream layer (5) of an adsorbent selectively adsorbent for the vaporized absorbent fluid contained in said ammonia depleted gas and a downstream layer (6) of an adsorbent selectively adsorbent for nitrogen.
