Clariant has launched a new high-performance ethyl benzene dehydrogenation catalyst Styromax UL3 for synthesis of ultra-low steam-to-oil ratio (also known as steam-to-hydrocarbon ratio, SHR). Company says, it produces styrene monomer far more efficiently than many other state-of-the-art catalysts. The new catalysts solves a critical problem in styrene monomer production. Styrene monomer is manufactured from ethyl benzene using superheated steam as energy source, and relies on catalysts to facilitate the dehydrogenation reaction. As generating steam consumes considerable energy, the latest plant process designs rely on ultra-low SHR conditions in order to reduce costs. However, previous generations of styrene catalysts have performed suboptimally at such low SHR conditions, demonstrating either favorable activity or selectivity, but not both. The higher activity of the catalyst increases yields, while its improved selectivity decreases the occurrence of by-products such as toluene and benzene, which are typically less valuable than styrene monomer. For producers, this directly translates into significant savings and increased productivity, company highlights benefits for users. Moreover, the catalyst’s optimal performance at ultra-low SHR ratios now makes styrene monomer production a much more sustainable process.
