Dongguan Juzhengyuan Technology Co., Ltd.’s propane dehydrogenation to high-performance polypropylene project has a total polypropylene production capacity of 1.2 million tons/year in two phases. The first phase of the 600,000 tons/year production capacity was put into production in 2019, and the second phase of the 600,000 tons/year production capacity was put into trial production in May 2023. The PDH unit adopts the patented CATOFIN technology of Lummus Corporation of the United States, which uses chromium-based catalysts to dehydrogenate propane into propylene in a fixed-bed reactor. (Source)

Shanghai, July 16, 2020 – Clariant announced today a second contract win for its CATOFIN catalysts with Dongguan Grand Resource Technology (DGR) in Dongguan, China. The company based its decision on the successful startup of its 600 KTA CATOFIN propane dehydrogenation (PDH) unit in October 2019. Together, both PDH units will represent 1.2 million metric tons annually of additional annual propylene capacity. Since 2017, CATOFIN Technology has now been selected for a majority of new PDH awards globally, representing 22 new PDH plants, or more than 15 million metric tons of propylene annually. (Source)
