Successful application of China Petroleum slurry catalyst

Recently, the polyethylene catalyst PSE-CX2 independently developed by the China Petroleum and Petrochemical Research Institute realized industrial application in the Lanzhou Petrochemical Mitsui slurry polyethylene plant for the first time, and produced more than 800 qualified heat-resistant polyethylene pipe resin L5050 products.
Ton, marking a zero breakthrough in the catalyst for the three-pot series slurry process independently developed by PetroChina
.

At present, three kettles in series are the main process for producing high-end polyethylene products
.

In response to the actual needs of the company, the Daqing Center of the Petrochemical Institute independently developed the three-tank multimodal polyethylene product special slurry catalyst PSE-CX2, which overcomes the continuous release of the activity of the titanium-based catalyst under high hydrogen conditions, combined with the technical reserves in the research and development of polyolefin catalysts.
The technical difficulties of the series can meet the performance requirements of the catalyst for tandem polymerization
.

This industrial test required complicated processes such as catalyst switching, single-to-three-tank polymerization process switching, and product brand switching, which increased the difficulty
