Styrene Catalyst Portfolio

Styrene monomer is an essential base chemical for the polymer industry. It is most commonly produced via catalytic dehydrogenation of ethyl benzene (EB).

The EB feed is mixed with superheated steam, and the gas is passed over the catalyst bed in a two- or three-reactor configuration. The process consumes vast amounts of heat, and must be operated under reduced partial pressures.

The key to economically and environmentally sustainable styrene production is the ethylbenzene (EB) dehydrogenation catalyst. Clariant’s StyroMax® catalyst series provides best-in-class performance, and suits all EB dehydrogenation technologies.

For plants experiencing reactor pressure drop, we also offer StyroMax rib-shaped catalysts, with a unique design to drastically reduce pressure drop by 30% to 50%. Learn more about our unique technology.

STYROMAX UL3

StyroMax UL3 is the first ethylbenzene dehydrogenation catalyst to offer ultra-high selectivity and ultra-low steam-to-oil (S/O) ratios. This makes it the most cost-efficient styrene catalyst globally.

It is also highly resistant to coke formation, and proven to promote reliable styrene production with the lowest steam consumption.

STYROMAX UL1

StyroMax UL1 features innovative proprietary technology that maintains outstanding robustness, making the styrene catalyst a game-changer for units operating at steam-to-oil (S/O) ratios between 1.1 and 1.35.

The highly active and selective ethylbenzene dehydrogenation catalyst offers impressive performance that quickly adapts to changes in operating conditions.

STYROMAX 9

StyroMax 9 is the latest generation of our styrene catalystsleading the global market for units with steam-to-oil (S/O) ratios above 1.3

Compared to previous catalysts, it offers much higher activity, and far greater resistance to deactivation.  Producers benefit from lower steam costs, higher yields, and longer production cycles.

Clariant's NiSat® 310 catalyst adds polishing touch to Evonik-tkIS HPPO process at propylene oxide plant in China
November 30, 2022
Clariant Catalysts has teamed up with Evonik and thyssenkrupp Industrial Solutions (tkIS) in a major propylene oxide project for one of China’s largest rubber producers. Qixiang Tengda is one of the leading global producers of carbon-four chemical products, such as methyl ethyl ketone and maleic anhydride. Expanding into the carbon-three value chain, the company’s new propylene oxide plant in Zibo city, Shandong province, relies on Evonik-tkIS HPPO technology to convert propylene in the presence of hydrogen peroxide (HP) directly into propylene oxide (PO). The plant will have an annual production capacity of 300,000 tons. more
