PROCESS FOR THE PREPARATION OF AMMONIA

摘要

Process for the preparation of ammonia by contacting an ammonia synthesis gas with ammonia catalyst particles arranged in a fixed bed, wherein the fixed bed comprises catalyst particles of the ammonia catalyst with a particle size being in the range of <1.5 mm and .gtoreq.0.2 mm. The process of the present invention improves the process performance of ammonia synthesis in terms of a higher ammonia product yield.
