AmoMax-10 - A novel Ammonia Synthesis Catalyst

摘要

This paper summarizes the features of a completely new generation of ammonia synthesis catalyst. The catalyst is still iron based, however, the iron oxide is of so-called wustite crystal structure. Results from extensive laboratory tests and from first charges in ammonia plants on commercial scale are discussed within the paper and confirm the higher activity of this catalyst. This novel ammonia synthesis catalyst allows a more efficient ammonia production and new ammonia plant flowsheets with smaller synthesis converter catalyst volume or lower temperatures and loop pressures. This high performance catalyst provides a very significant contribution to an improved ammonia plant efficiency and economy.
