BCE high activity ethylene slurry polymerization catalyst was successfully developed

The BCE high activity ethylene slurry polymerization catalyst independently researched and developed by Beijing Research Institute of Chemical Industry has passed the appraisal of the Ministry of Science and Technology of China Petrochemical Corporation. This is another innovative achievement in the research field of slurry-based polyethylene catalysts following the successful development of the BCH catalyst.

With the development of polyethylene technology and the development of high-performance resin products, industrial production puts forward higher requirements for catalysts. Japan, South Korea, and other countries are also conducting research on high-activity slurry polymerization catalysts, and have also stepped up technology promotion in Southeast Asia and China, threatening BCH catalysts. To this end, the Beijing Chemical Research Institute began the research and development of a new generation of ethylene slurry polymerization catalyst in January 2004.

In more than a year's time, the Beihua Institute of Science and Technology personnel conducted a lot of exploration and research, has overcome many difficulties, and achieved breakthroughs at the end of September last year, completed the BCE catalyst dissolution system selection, catalyst formulation research and other experimental research and catalysts Small test formula stereotypes. Compared with the existing similar catalysts, BCE catalysts have the advantages of high catalytic activity, narrow polymer particle size distribution, low fines content, and high polymer bulk density. At the same time, the BCE catalyst has the characteristics of simple preparation process, low production cost, and less extractable polymer hexane. BCE catalyst technology has complete independent intellectual property rights and has now applied for 6 Chinese patents and 1 foreign patent.
