Recently, the metallocene polypropylene catalyst independently developed by the Beijing Research Institute of Chemical Industry successfully completed the first industrial application test in the ring pipe polypropylene process unit of Zhongyuan Petrochemical, and produced homopolymerized and random copolymerized metallocene polypropylene resins with excellent performance. China Sinopec became the first company in China to successfully independently develop metallocene polypropylene technology.
Metallocene polypropylene has the advantages of low soluble content, high transparency and high gloss, and is an important direction for the transformation and upgrading of the polypropylene industry and high-end development. Beihua Institute started the research and development of metallocene polypropylene catalyst in 2012. After small test, model test and pilot test scale-up preparation, it solved technical problems such as catalyst structure design, preparation process and catalytic activity optimization, and successfully developed metallocene polypropylene catalyst. Propylene catalyst technology and the production of catalyst products. In the comparative evaluation under the same polymerization conditions, the catalyst has higher activity than the imported catalyst, and the prepared polypropylene product has better particle shape and no agglomeration.
Since November this year, the catalyst has successively completed industrial tests in the Hypol process polypropylene plant of Yangzi Petrochemical and the ring pipe process polypropylene plant of Zhongyuan Petrochemical, and obtained good verification results. This industrial test in Zhongyuan Petrochemical is the first time in China to produce random copolymerized metallocene polypropylene on a ring pipe polypropylene device, which has laid a solid foundation for the high-end development of Sinopec’s polypropylene industry.
