近日,中石油石油化工研究院自主研发的气相聚乙烯(PE)浆液型催化剂(PGE-101),在吉林石化27.4万吨/年线型低密度聚乙烯装置上完成了超冷凝态生产条件下的工业推广,各项指标达到了进口催化剂的水平。PGE-101在超冷凝的苛刻条件下实现了装置平稳运行,工艺控制稳定,催化活性超过20000倍,产品堆积密度达到0.38-0.39g/cm3.与国内外同类催化剂相比,PGE-101具有活性释放稳定、聚合产品细粉含量低、粒径分布窄、装置结片 Recently, PGE-101, a self-developed gas phase polyethylene (PE) slurry catalyst researched and developed by PetroChina Petrochemical Research Institute, has completed its production under a supercritical condensing condition at a production capacity of 274,000 t / y linear low density polyethylene in Jilin Petrochemical Co., Industrial promotion, the indicators reached the level of imported catalysts. PGE-101 has the advantages of stable operation, stable process control, over 20000 times catalytic activity, and product bulk density of 0.38-0.39g / cm3 under the conditions of supercondensation.Compared with similar catalysts at home and abroad, PGE-101 has activity Stable release, low powder content of polymer product, narrow particle size distribution, device chip
