Munich/Germany — The plant will be located in Qingdao, Shandong Province, China and have the capacity to produce 900,000 metric tons per annum (MTA) of propylene when completed.

The project is based on CB&I’s Catofin propane dehydrogenation technology combined with Clariant’s custom-made Catofin catalyst and Heat Generating Material. The partners have previously collaborated on numerous projects to design specialized propane dehydrogenation units both in China and around the world.


The Catofin process is used to produce olefins, such as propylene or isobutylene, from light paraffin feedstocks. Features mentioned by the company include a high operational reliability, efficiency, and maximum conversion of raw materials at optimum reactor pressure and temperature. Incorporated into the process, Clariant’s patented metal-oxide Heat Generating Material increases the catalyst’s selectivity and yield, while conserving energy and reducing emissions, the company claims.

Jinneng Science & Technology Company, is a major industrial producer of fine chemical products and coal chemical products. As sustainability is a core component of their business strategy, the company integrates energy efficiency, environmental protection and innovative recycling practices into all production processes.
