    Recently, PetroChina Petrochemical Research Institute independently developed gas-phase polyethylene (PE) slurry-type catalyst (PGE-101), in Jilin Petrochemical 274,000 tons / year line-type low-density polyethylene plant completed the industrial promotion under the conditions of ultra-condensation production, the indicators reached the level of imported catalysts.
    PGE-101 achieves smooth operation of the unit under the harsh conditions of ultra-condensation, stable process control, catalytic activity of more than 20,000 times, product accumulation density of 0.38-0.39g/cm3. Compared with similar catalysts at home and abroad, PGE-101 has the characteristics of stable active release, low fine powder content of polymerized products, narrow particle size distribution, fewer device nodes, sensitive hydrogen adjustment of catalysts, outstanding copolysis performance, and good polymer particle form.
    of Daqing Chemical Research Center of The Institute of Petrochemical Research, through the combination of carrier surface modification and spray drying, have overcome the core technical problems of particle form control in catalyst preparation. In the process of starting operation, researchers in-depth understanding of the technical difficulties of ultra-condensation operation, developed a technical program, clear catalyst quality indicators, and in the country's most advanced gas phase full density polyethylene pilot device carried out 9 catalyst pilot, to solve the ultra-condensation operation of the fluidized bed reactor catalyst induction time, system fluid accumulation, fluidization retention, reactor nodules and other technical problems.
    at present, petrodrug polyethylene plant production capacity of 2.6 million tons / year, the annual demand for slurry-type catalyst 100 tons, but the market is almost foreign companies and a few domestic catalyst factories monopoly. Imported catalysts sell at high prices, have long purchase cycles, and the stability of catalyst batches is poor, often resulting in fluctuations in device production, transition materials, product quality but not off.
