Clariant provides Wanhua with maleic anhydride catalyst

On July 12, Clariant announced that it had won an important contract from Wanhua Chemical Group to provide catalysts for its new maleic anhydride project.

It is reported that the production plant currently under construction by Wanhua Chemical is one of the largest maleic anhydride production plants in the world, with a designed annual production capacity of 200,000 tons. Its production process will be based on Clariant's SynDane catalyst. The device will be located in Yantai City, Shandong Province, and is scheduled to start production in 2023.

According to reports, Clariant's SynDane catalyst is well suited for the new production process, having previously been validated in performance tests using the MAN DWE reactor. In addition, due to its extremely low pressure drop, SynDane can further improve the production efficiency and energy efficiency of the new process. The special structure and chemical composition of the catalyst also increase the selectivity to maleic anhydride, thereby maximizing the product yield.

At present, China is phasing out the use of non-degradable plastics, and maleic anhydride is an important base for the production of biodegradable plastics polybutylene adipate/terephthalate (PBAT) and polybutylene succinate (PBS). material, the market demand is huge.

In addition, Wanhua Chemical said that the company also selected another Clariant catalyst, EnviCat N2O-S, for its nitric acid plant operating in Ningbo to efficiently purify exhaust gas containing nitrous oxide. Nitrous oxide is a greenhouse gas that has a great impact on global climate change. The move is expected to convert up to 95 percent of nitrous oxide emissions into harmless oxygen and nitrogen.
