Patent number: 10618817Abstract: A method and device for producing ammonia from a syngas in a heterogeneous gas catalysis process in at least two reaction devices connected in series. Each reaction device includes at least two catalyst beds through which the syngas is conducted and in which an at least partial conversion of the syngas into the product gas is carried out. At least one first heat exchanger is provided in the first reaction device, and the fresh syngas is pre-heated in the first heat exchanger. The syngas exiting the first catalyst bed and which includes the product and non-converted reactants is cooled before entering the second catalyst bed. According to an embodiment of the invention, the pre-heating process is carried out in a first heat exchanger arranged between the first and the second catalyst bed.
