摘　　要：将丙烯聚合用高活性低细粉含量IC2催化剂在气相法Horizone工业装置进行了试用。结果表明:与对比催化剂相比,IC2催化剂活性提高了27%,氢调性能接近,共聚性能略差,催化剂孔隙率略高;采用IC2催化剂制备的聚丙烯粉料的细粉含量明显低于采用对比催化剂;采用IC2催化剂时反应器的料位需要适当调低,所制聚丙烯的等规指数与采用对比催化剂接近,产品性能接近。The high activity and low fine powder polypropylene catalyst IC2 has been industrially applied in Horizone gas phase process.The application results show that the activity of IC2 catalyst is higher than that of the reference catalyst by 27%,and their hydrogen regulation performance is similar.The copolymerization performance of IC2 is slightly worse and the porosity of the catalyst is slightly higher than those of the contrast catalyst.The fine powder content of the powder produced by IC2 is significantly lower than that of the reference catalyst.The powder level of the reactor needs to be lowered when using IC2 catalyst.The isotacticity of the product produced with the IC2 catalyst is close to that of the contrast catalyst,and the product performance is similar.
