AmoMax 10 Plus - A new era of ammonia synthesis catalysts

AmoMax^® 10 Plus is Clariant's latest generation of wustite-based ammonia synthesis catalysts. The catalyst is based on the proven ammonia synthesis catalyst AmoMax 10 with an improved promoter set. The optimization of concentration and ratio of the promoter system lead to higher activity, higher stability and a faster startup of AmoMax 10 Plus. The significantly increased activity allows operation with a higher per pass conversion and lower loop pressure, which can be utilized for added ammonia production and/or energy savings. The higher stability and improved water resistance increase the catalyst lifetime and enable a faster catalyst reduction.

AmoMax-Casale

AmoMax®-Casale is a new ammonia synthesis catalyst jointly developed by Casale and Clariant particularly for use in Casale ammonia converters. AmoMax-Casale 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 to reduce the loop recycle rate and the loop pressure and/or to increase the ammonia production. By optimizing the plant’s overall efficiency, the customers can generate higher profitability by either benefiting from energy savings and reducing the CO2 footprint or monetizing its increased ammonia production.

AmoMax 10

AmoMax® 10 is a wustite-based ammonia synthesis catalysts with a unique promoter system that provides much higher activity and stability than magnetite-based catalysts. This improves conversion at low operating temperatures and at more thermodynamically favorable conditions, thus raising ammonia yields. Due to reduced loop recycles and loop pressure, it also saves energy and reduces CO2 emissions.

ActiSafE

Clariant has developed a safe, efficient and accurate method for measuring water vapor formation and ammonia concentration during ammonia synthesis catalyst activation. ActiSafETM, the latest innovative technology provides advantages, such as continuous real-time measurements. The real-time data allows plant operators to respond quickly to changes in water vapor formation and to optimize the reduction procedure. This not only saves time and avoid catalyst poisoning but also extends the lifespan of the catalyst leading to higher ammonia production.
