摘要： Process for the preparation of ammonia comprising steps of contacting an ammonia synthesis gas with an ammonia synthesis catalyst arranged as reaction zone in one or more catalyst tubes; cooling the reaction zone by heat conducting relationship with a cooling agent; and withdrawing an ammonia rich effluent stream from the reaction zone. The converter comprises at least one catalyst tube adapted to receive ammonia synthesis gas and to hold a reaction zone of ammonia synthesis catalyst and a cooling agent at the shell side of the catalyst tubes.
