Evonik to license hydrogen peroxide tech to Pingmei Shenma in China

German chemicals firm Evonik says it will license its hydrogen peroxide (H2O2) production technology to China’s Pingmei Shenma Group Nylon Technology (Shenma) to build an H2O2 plant with a capacity of 200 kilotonnes/year in Pingdingshan, Henan Province. Start-up of the plant is expected in 2026.

The H2O2 produced in the new plant will be captive-used for Shenma’s own production of caprolactam – a key precursor for nylon 6.

Shenma is a major player in the Chinese chemical fibre industry, covering the entire value chain for nylon 6 and nylon 66. The company plans to expand its caprolactam production capacity to 600 kilotonnes/year by 2026. By simultaneously upgrading its H2O2 production technology and boosting on-site capacity, Shenma will benefit from supply security and guaranteed quality for its caprolactam production.

And the selection of Evonik’s fluidised-bed technology will enable Shenma to fulfil stringent new national requirements for process safety in the production, it adds.

Michael Träxler, head of Evonik’s Active Oxygens business line, stated, “Evonik offers easy-to-operate and safe technology, fast delivery, and long-term partnership – factors which are of great value and very much appreciated by our customers.”

The agreement with Shenma marks Evonik’s third licensing project for hydrogen peroxide production in China. Most recently, Fuhua Tongda Chemicals Company began construction on a 200 kilotonnes/year plant based on Evonik technology in Leshan, Sichuan Province, in 2024.
