Clariant catalyst delivers strong performance at Wanhua maleic anhydride plant
Clariant’s SynDane 3142 LA catalyst has achieved solid performance at Wanhua Chemical's maleic anhydride plant in Yantai, China. The catalyst, which started up in 2024, has demonstrated very good operational results, delivering on its promise of efficiency and sustainability benefits.
Wanhua Chemical's maleic anhydride plant in Yantai, China, powered by Clariant's high-performing SynDane 3142 LA catalyst.
The SynDane catalyst is achieving notably high yields and significantly reduced byproduct formation at the Yantai facility, one of the world's largest maleic anhydride units with a production capacity of 200,000 tons per year. SynDane's innovative design continues to drive sustainability through reduced pressure drop and lowered energy consumption.
“We are pleased with the strong performance of our SynDane catalyst at Wanhua's facility. The high selectivity and yield achievements demonstrate how our innovative solutions deliver long-term value,” said Nora Schiefenhoevel, Vice President and Head of Clariant Specialty Catalysts.
Clariant's Applied Catalyst Technology team based in Panjin, China has provided comprehensive technical service throughout the project. Their expertise and dedication have been one of the key factors in achieving the current strong operational results.
SynDane 3142 LA is a selective oxidation catalyst featuring Clariant's proprietary doublealpha shape, which provides physical and chemical properties that maximize selectivity for maleic anhydride production while significantly reducing pressure drop compared to conventional ringshaped catalysts. This patented doublealpha design gives producers a distinct advantage with higher productivity at lower process and energy costs.
SynDane also enables very good maleic anhydride quality by minimizing the formation of undesired by-products, greatly reducing plant downtime. Thanks to its operating stability, SynDane offers a long lifecycle of more than 5 years. The proprietary doublealpha shape represents a significant innovation that differentiates SynDane 3142 from conventional ring-shaped catalystst.
