China: Production of Propylene Oxide Evonik and Thyssenkrupp Industrial Solutions License HPPO Technology to China

Evonik and Thyssenkrupp Industrial Solutions have granted a license for HPPO Technology to Zibo Qixiang Tengda Chemical to produce propylene oxide. Corresponding agreements were signed by the parties in Guangzhou in China.

Guangzhou/China — Propylene oxide is a material used mainly for the production of polyurethane foams, which are used in automotive parts, furniture upholstery, thermal insulation, coating materials, sports shoes, and other sports equipment. The global market for polyurethane is expected to grow with China being one of the most important growth markets. However, green HPPO Technology is also gaining in importance. That is why on top of developing the traditional hydrogen peroxide business, the Active Oxygens Business Line of Evonik is promoting this technology through licensing. Together with Thyssenkrupp Industrial Solutions, the company has now granted a license for the production of propylene oxide to the Chinese manufacturer Zibo Qixiang Tengda Chemical.

In addition, Evonik has licensed the production of hydrogen peroxide for the exclusive supply of the propylene oxide plant to Qixiang Tengda. Furthermore, the companies have entered into a long-term agreement for the supply of the respective HPPO catalyst.

With environmental awareness on the rise in China, HPPO is the technology of choice for sustainable production of propylene oxide because it produces no major byproducts apart from water, says Claus Rettig, Chairman of the Board of Evonik Resource Efficiency segment.

In the next few years Qixiang Tengda will construct a plant complex at the Zibo site (in China’s Shandong province), where up to 300 kmt of propylene oxide and the amount of H₂O₂ required for the HPPO process will be produced annually. The initial planning phase will start by the middle of August 2019. The plant is expected to come on stream in the first half of 2022.
