The Catalyst that changed the Game for Ammonia Synthesis

amomax 10

AmoMax® 10 is a wustite-based ammonia synthesis catalyst with a unique promoter system that provides excellent stability and much higher activity compared to magnetite-based catalysts.

The innovative catalyst improves conversion at low operating temperatures and thermodynamically favorable conditions, thus raising ammonia yields. As an added benefit, reduced loop pressure and recycle rates save energy and reduce CO2 emissions.

FROM MAGNETITE TO WUSTITE BASED CATALYSTS

  • Ammonia Catalysts

    Ammonia catalysts must enable more efficient ammonia synthesis today than ever before. With a growing demand on ammonia for the production of chemical fertilizers, and increasing volatility of feedstock prices and energy resources, ammonia producers need reliable solutions to succeed in this highly competitive market. Clariant’s ammonia catalysts are proven to increase efficiency and productivity while minimizing costs. They offer superior performance to maximize ammonia yields, and allow sustainable management of resources to reduce energy consumption in ammonia production. We offer a complete range of ammonia process catalysts, and support you with comprehensive technical services from plant design or upgrades to ensuring optimal catalyst performance. Clariant collaborates with renowned technology partners, such as KBR and Casale, to provide you with the ideal solution based on your specific requirements. more

  • AmoMax 10 Plus

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

  • 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. more

  • 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. more
