摘要
在中国石油兰州化工研究中心75 kg/h聚丙烯中试装置上进行了进口Basell ZN 111-4催化剂的聚合反应性能评价实验。结果表明,ZN 111-4催化剂具有较高的聚合活性和氢调敏感性,产品的等规度可在较大范围内调整,催化剂活性释放平稳,抗杂质干扰能力较强。在催化剂流量和质量浓度分别为0.18 mL/min及100 g/L,n(氢气)/n(丙烯)为0.004,m(三乙基铝)/m(给电子体)为1.08的工艺条件下,当丙烯的含水量为3.54 mg/L时,ZN 111-4催化剂的活性[m(聚丙烯)/m(催化剂)]高达31 480。
The reaction performance of import catalyst ZN 111-4 was evaluated in the 75kg/h polypropylene pilot unit of Lanzhou Petrochemical Research Center.The results showed that catalyst ZN 111-4 had higher activity and better hydrogen response behavior,tolerance to impurities and activity stability.The isotacticity of the product could be adjusted in a wide range.Under the conditions of catalyst flow 0.18mL/min,catalyst mass concentration 100g/L,the mass ratio of triethyl aluminum to electro donor 1.08,the activity [m（polypropylene）/m（catalyst）]of ZN 111-4 reached 31480 when the moisture in propylene was 3.54 mg/L.
