Clariant ammonia synthesis catalyst started up at BASF ammonia plant in Antwerp

BASF – the inventor of the Haber Bosch process – has already installed Clariant's previous catalyst generation, AmoMax 10, at their BASF/Yara joint production plant in Freeport, Texas, USA. Based on the catalyst's performance, BASF elected to use a Clariant catalyst again, this time the new AmoMax 10 Plus, which offers an additional boost in activity, stability, and startup speed. Compared to the previous generation, AmoMax 10 Plus allows operation at lower pressure (up to 10 bar) and a lower recycle ratio (up to 1% more ammonia at the reactor outlet), thereby conserving more energy and reducing CO₂ emissions.

Stefan Heuser, Senior Vice president and General Manager at Clariant Catalysts, stated: "As one of the frontrunners in the field of ammonia synthesis catalysis, we are always looking for solutions to improve our customers' efficiency, safety, and economy. AmoMax 10 Plus is an excellent example of this. We are honored to have BASF as the first commercial reference for our innovative catalyst and look forward to demonstrating the further advantages of AmoMax 10 Plus."

AmoMax 10 Plus is Clariant's latest generation of wustite-based ammonia synthesis catalysts. It is founded on the AmoMax 10 and is designed with a further improved promoter set based on a deep and profound understanding of the reaction mechanism. This optimisation leads to higher activity, improved stability, and faster start-up. The strong activity of AmoMax 10 Plus allows operation with a higher per pass conversion at lower operating pressure. Consequently, it can increase ammonia production (up to 3%) and reduce energy consumption and CO₂ footprint.

Compared to the previous version AmoMax 10, AmoMax 10 Plus allows significant energy savings with an expected CO₂ reduction of up to 125 000 t CO₂ emissions for a 2000 tpd ammonia plant over the course of the typical catalyst lifetime of 15 years. On a yearly basis, this equals the CO₂ emissions of more than 1600 cars.
