Clariant China 2025-09-25 14:20:51

Clariant, a specialty chemicals company focused on sustainability, recently announced,The SynDane™ 3142 LA catalyst performed excellently in the maleic anhydride unit at Wanhua Chemical in Yantai.Since its startup in 2024, the catalyst has demonstrated excellent operational performance, fulfilling its commitments to efficiency and sustainability.

The design of the device for the year.Production capacity of 200,000 tons.It is one of the largest maleic anhydride production facilities in the world. Currently, the SynDane catalyst is performing excellently in the facility, especially its high yield significantly reduces the generation of by-products.SynDane's innovative design achieves lower pressure drop and reduced energy consumption, helping customers achieve sustainable operations.

Global Vice President of Specialty Catalysts Business at ClariantNora SchiefenhoevelThe phrase "" translates to "indicates that" in English.We are pleased with the outstanding performance of the SynDane catalyst at the Wanhua facility. Its high selectivity and high yield results fully demonstrate the long-term value that our innovative solutions create for our customers. For Clariant, this project holds special significance as it allows us to provide comprehensive sustainable solutions with our rich portfolio of catalysts, helping to enhance energy efficiency and productivity.

Wanhua Chemical Group is headquartered in Yantai, Shandong, and is one of the largest chemical enterprises in China, ranking among the top 20 chemical companies in the world.

The Clariant Applied Catalysis Technology team in Panjin provided comprehensive technical support for the project throughout.The team's expertise and dedication are key factors in achieving the current outstanding operational results. The recently implemented Clariant's cutting-edge digital platform, CLARITY, has further deepened the collaboration between both parties, enabling efficient data exchange and analysis, and continuously optimizing device performance.

Wanhua Chemical's Yantai maleic anhydride plant adopts Clariant's SynDane 3142 LA catalyst.

SynDane 3142 LA is a selective oxidation catalyst featuring Clariant's patented dual alpha design.Compared to traditional ring-shaped catalysts, its unique physical and chemical properties can achieve the highest selectivity in the production of maleic anhydride while significantly reducing pressure drop. This innovative design offers manufacturers significant advantages by achieving higher productivity with lower process and energy costs. SynDane effectively suppresses the formation of by-products, ensuring excellent quality of maleic anhydride and greatly reducing downtime of the plant. With its high stability,SynDane has a long cycle life of over 5 years. The proprietary double-alpha shape design is a major innovation, significantly differentiating SynDane 3142 LA from conventional ring-shaped catalysts.
