Clariant, a global leader in specialty chemicals, has introduced its most advanced ethylbenzene dehydrogenation catalyst yet—StyroMax UL-100. Developed in collaboration with Technip Energies, this next-generation catalyst marks a significant technological leap in styrene production by enabling ultra-low steam-to-oil (S/O) ratios of just 0.76 by weight. This advancement redefines efficiency standards in styrene monomer (SM) manufacturing, offering plant operators the ability to dramatically cut down steam usage without compromising on production output.

StyroMax UL-100 has been specifically designed for flexible deployment, whether through drop-in replacements in existing units, plant revamps, or new grassroots facilities. By integrating seamlessly into Technip Energies’ proprietary styrene technology—licensed through Badger Process Technology—the catalyst enhances both economic and environmental performance for producers.

Historically, the industry has struggled to reduce steam consumption without affecting yield. Previous generations of catalysts typically operated at S/O ratios around 1.02 by weight. The StyroMax UL-100 surpasses this benchmark, allowing for significantly lower ratios while maintaining high catalyst activity and selectivity. This results in reduced energy demand, lower operating costs, and a smaller carbon footprint—key benefits for companies looking to meet stricter sustainability targets.

“This breakthrough is a result of close collaboration with Technip Energies and attentive engagement with our customers,” said Gene Mueller, Head of Ethylene and Vice President of Clariant’s Business Unit Catalysts in the Americas. “StyroMax UL-100 represents a transformative step forward in catalyst innovation. It empowers customers to meet their efficiency and sustainability goals more effectively.”

Wei Cai, Chief Technology Officer at Technip Energies, echoed this sentiment: “Our partnership with Clariant reflects our shared mission to deliver sustainable and high-performance solutions. With StyroMax UL-100, our clients can significantly improve operational efficiency, reduce energy consumption, and cut greenhouse gas emissions—contributing to a cleaner, more sustainable future for styrene production.”

Available to all Badger-licensed facilities—whether existing, revamped, or new—StyroMax UL-100 brings tangible value across a range of performance indicators. Key advantages of the new catalyst include:

• Operation at an industry-first low S/O ratio of 0.76 by weight
• Enhanced catalyst performance with high selectivity
• Lower energy use and operating expenses
• Improved environmental footprint and sustainability profile
• Seamless compatibility with Technip Energies’ Badger technology

With StyroMax UL-100, Clariant and Technip Energies set a new benchmark in the pursuit of efficient, eco-conscious styrene production.
