Clariant SynDane™ Catalyst Achieves Performance Milestones at Wanhua Maleic Anhydride Plant
Clariant recently announced the solid performance of its SynDane 3142 LA catalyst at Wanhua Chemical’s maleic anhydride plant in Yantai, China. Wanhua Chemical Group is one of the largest chemical producers in China and ranks among the top 20 globally. The catalyst, which started up in 2024, has demonstrated very good operational results, delivering on its promise of efficiency and sustainability benefits. The SynDane catalyst is now achieving excellent performance metrics, with 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 t/y. SynDane’s innovative design continues to drive sustainability through reduced pressure drop and lowered energy consumption. 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. The recent implementation of Clariant’s state-of-the-art digital platform - CLARITY has further enhanced collaboration, enabling efficient data exchange and analysis to continuously optimize plant performance. 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.
