【摘要】 国产Ｎ 催化剂在聚丙烯装置上进行了长周期工业应用，通过对其产品的各项性能与进口催化剂的比较、对Ｎ 催化剂总体特性的评价，确定其聚合过程对氢调较敏感，催化剂活性较好。Ｎ 催化剂可以替代进口催化剂进行工业化生产，每年可创经济效益２９２ 万元。更多还原

【Abstract】 Long period commercial application of N catalyst was carried in polypropylene plant. Through comparing the product property with the imported reference one, it was concluded that N catalyst was more sensitive to the hydrogen content in polymerization as well as better activity. The N catalyst was suggested to replace the imported G catalyst for industrial production.更多还原
