Clariant’s ammonia synthesis catalyst AmoMax-Casale has been selected for a green ammonia project being jointly developed by The Hydrogen Utility (H2U) and Casale.

The project will commence with two pilot plants at H2U’s Eyre Peninsula Gateway™ in South Australia, with the aim of expanding the technology to various plants, industry sectors and regions.

Jointly developed by Clariant and Casale for use in Casale ammonia converters, AmoMax-Casale is a customised evolution of the wustite-based catalyst AmoMax 10. The catalyst’s optimised promoter package 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. By optimising the plant’s overall efficiency with AmoMax-Casale, operators can significantly reduce their energy consumption or enjoy greater productivity at the same operating costs.

Stefan Heuser, Senior Vice President and General Manager of Clariant Catalysts, commented: “Clean energy is the only way in the future, and Clariant is fully committed to decarbonizing the chemical industry through sustainable innovations like AmoMax-Casale. Our award-winning catalyst is one of the most important breakthroughs in the ammonia industry and one that we believe will pave the way for further green ammonia projects that contribute to solving the future energy challenge. We are excited to participate in the highly ambitious H2U project with our technology partner Casale and look forward to driving change together.”

Federico Zardi, CEO at Casale, stated: “The world needs to turn the page and fight climate change. In this context, Casale is ready to accept the challenge and to contribute to the development of sustainable plants to produce ammonia and derivatives by reducing or even eliminating emissions.”
