Tailor-made Catalyst for Casale Ammonia Converters

amomax-casale

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.

MAIN BENEFITS

AWARD WINNING INNOVATION

AmoMax-Casale was recognized by the ICIS Magazine and the Swiss Chemical Society. The catalyst was awarded with the ICIS Innovation Award for Best Sustainable Process and the Sandmeyer Award.

COMBINING EXPERTISE LEADS TO SUPERIOR RESULTS

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

    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. 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

  • 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
