Ammonia catalyst Clariant Catalyst (Munich, Germany; www.clariant.com) and Casale SA (Lugano, Switzerland; www.casale.ch) have developed a new ammonia synthesis catalyst for sustainable CO2 reduction. Based on Clariant’s AmoMax 10 — a wüstite-based alternative to traditional magnetite-based catalysts — the AmoMax-Casale catalyst is said to have a significantly higher activity than previous catalysts. Developed using Clariant’s catalyst expertise and Casale’s ammonia converter-design know-how, AmoMax-Casale delivers an up to 30% higher efficiency factor, thanks to a larger active surface area than previous generations of AmoMax, thereby significantly lowering the energy consumption of an ammonia plant. The catalyst’s higher activity allows operation of the ammonia synthesis loop with considerably less pressure, which means the plant consumes less energy to produce ammonia, and hence generates less CO2 emissions. The higher catalyst activity means higher conversion, so the plant will consume less energy for the recirculation of the process gas in the reactor loop. The combination of a more active catalyst with the Casale design of converter internals makes the difference, says Clariant. A typical ammonia plant producing…
