AmoMax®-Casale is a new ammonia synthesis catalyst jointly developed by Casale and Clariant for use in Casale ammonia converters.
The catalyst is a customized evolution of the well-known, wustite-based catalyst, AmoMax® 10. While retaining the same superior resistance to aging, poisoning, and mechanical strength, AmoMax-Casale is significantly more active. With an optimized promoter package, AmoMax-Casale provides a larger active surface area and improved diffusion properties, resulting in a 30 % higher efficiency index compared to the wustite-based reference.
This allows a reduction of the loop pressure and recycle rates and/or an increase in ammonia production.
Optimizing the plant’s overall efficiency with AmoMax-Casale helps operators to generate higher profitability by either benefiting from energy savings and reducing the CO2 footprint or by monetizing the increased ammonia production.
