Abstract
Means are disclosed for lowering the temperature of the gaseous effluent from the first catalyst bed in a continuous ammonia synthesis process in which a syngas mixture containing nitrogen and hydrogen is passed sequentially over two or more catalyst beds containing ammonia synthesis catalyst. This cooling, effected to promote the exothermic ammonia-forming reaction, is accomplished by subjecting the gaseous effluent from the first catalyst bed to heat exchange in a high temperature heat sink, preferably after having undergone heat exchange with the synthesis gas feed to the first catalyst bed, to control the temperature of the effluent entering the second catalyst bed to a desired level.
