Clariant Expanding Maleic Anhydride Catalyst Production in China

Clariant said it will significantly expand the capacity of its catalysts production facility in Panjin, Liaoning province, Northeast China.

A double-digit CHF million investment will further optimize the existing facility and enable the creation of a new state-of-the-art production line for Clariant’s SynDane maleic anhydride (MA) catalyst.

“Asia-Pacific, and especially China, is the main growth market and therefore it is vital that we continue to enhance our presence and customer proximity,” said Hans Bohnen, Clariant’s chief operating officer.

The project will allow Clariant to enable its customers to meet the growing global demand for MA, as production is expected to jump from 1.75 million tons in 2018 to 2.07 million tons in 2022, per IHS Markit Chemical Economics Handbook, November 2018.

MA is a fundamental component of polymers and coatings used in the construction, automotive, marine, and energy industries.

Clariant’s SynDane catalysts are optimized for cost-efficient MA production via selective oxidation of n-butane in fixed-bed tubular reactors. Thanks to their innovative microstructure and chemical composition, they offer superior yield, selectivity and operating stability. This greatly reduces the formation of by-products (such as acrylic acid and acetic acid) as well as their downstream polymerization, thus minimizing downtime for equipment.

Since 2007, Clariant has produced SynDane MA catalysts at the Panjin plant as a joint venture with North Huajin Chemical Industries Group Corporation. The production site in Panjin engages more than 140 employees in manufacturing catalysts and adsorbents for the production of butane-based maleic anhydride, ammonia, hydrogen, and methanol, as well as other applications.
