    Abstract: Process and reactor for the preparation of ammonia at elevated pressure and temperature in an ammonia reactor, wherein a process stream of ammonia synthesis gas is successively passed through at least three catalyst beds with intermediate cooling of partially reacted synthesis gas leaving the catalyst beds by heat exchange in heat exchangers arranged between each catalyst bed. The process stream is obtained by combining prior to introduction into a first catalyst bed, a first feed stream of synthesis gas having been preheated through indirect heat exchange during the intermediate cooling of the partially converted synthesis gas and a second feed stream of synthesis gas for adjustment of temperature of the process stream. The first feed stream is passed successively through the interbed heat exchangers for cooling the partially converted synthesis gas and space velocity of the synthesis gas is adjusted to be substantially in the same range in all catalyst beds.
