| 摘 要： | 考察了JK-1催化剂在中国石油大庆石化公司淤浆聚合高密度聚乙烯(HDPE)装置上的应用情况并与BCH催化剂进行了比较。结果表明,使用JK-1催化剂反应温度平稳可控,生产过程稳定,重要工艺参数可控;母液固含量小于5.2 g/L;催化活性m(HDPE)/m(催化剂)]高达21.9 kg/g;聚合期间熔体流动速率变化范围窄,仅为0.093～0.114 g/min;使用JK-1催化剂可获得密度波动范围为950.9～952.0 kg/m3,平均堆密度为0.368 g/cm3,平均粒径为354μm的HDPE颗粒。

| Abstract: | The industrial application of JK-1 catalyst for ethylene slurry polymerization was conducted and compared with home-made catalyst BCH in a high density polyethylene（HDPE） unit of Daqing Petrochemical Company,PetroChina.The results showed that using JK-1,the main process parameters,such as reaction temperature,were stable and controllable,and the operation was smooth.The solid mass fraction in mother liquor was less than 5.2g/L,the catalyst activitym（HDPE）/m（catalyst）]reached up to 21.9kg/g,the melt flow rate varied in a relatively narrow range of 0.093-0.114g/min.And the catalyst JK-1 based HDPE powders were obtained with density fluctuation range of 0.9509-0.9520g/cm3,average bulk density of 0.368g/cm3 and average particle size of 354μm. |
