采用扫描电子显微镜、激光粒径分析仪等表征了PGE-201型催化剂的形态，同时用PGE-201型催化剂在Unipol工艺的线型低密度聚乙烯（LLDPE）装置上进行为期90天的长周期运行试验，并与原来使用的M型催化剂进行了对比。结果表明：PGE-201型催化剂颗粒形态好，氢调敏感性好，共聚合性能与M型催化剂相当，活性可达5~8kg/g；用PGE-201型催化剂生产的LLDPE粉料的细粉含量更少、粒径分布更均匀、堆密度达0.35~0.40g/cm3，力学性能与光学性能均有显著提高。

The morphology of PGE-201 catalyst was characterized by scanning electron microscope (SEM) and laser particle size analyzer. Ninety days long period running trial was performed with PGE-201 catalyst on a Unipol process linear low density polyethylene (LLDPE) plant, and compared to that with M catalyst which was used on the plant. The results indicate that PGE-201 catalyst exhibits good particle morphology and hydro-gen response, its copolymerization performance is similar to that of M catalyst and its catalytic activity can reach 5-8 kg/g. The LLDPE powder produced with PGE-201 catalyst has less fine powder percentage and more even particle size distribution. The bulk density of the LLDPE product is 0.35-0.40 g/cm3. Moreover, the mechanical properties and optical properties of the product are improved significantly.
