摘　　要：采用BCE-H200催化剂在350 kt/a Hostalen ACP工艺高密度聚乙烯(PE-HD)装置完成ACP7000F膜料的工业试验。利用熔体流动速率、凝胶渗透色谱、力学性能测试等方法考察催化剂、聚乙烯粉料及膜料的综合性能。结果表明,BCE-H200催化剂具有较高的活性,较平稳的氢调敏感性和优异的共聚性能。与参比催化剂相比,BCE-H200催化剂活性提高87.5%,氢气单耗降低12.5%、1-丁烯单耗降低13.1%,所得聚乙烯粉料细粉少、平均粒径更大。由BCEH200催化剂生产的膜料各项力学性能更优,高负荷下鱼眼数量更少,符合企业生产标准。BCE-H200催化剂可替代进口催化剂生产高性能膜料树脂。经分析,参比催化剂膜料上形成的鱼眼主要组成为高分子量、低结晶度的聚乙烯。The industrial scale production for a film-grade PE-HD resin with a commercial brand of ACP7000F was suc-cessfully carried out on a Hostalen ACP industrial installation with a yield of 350 kt·a^(-1) using a BCE-H200 catalyst.The general performance of the resultant PE-HD resin and its film as well as the catalyst was evaluated by melt flow rate,gel permeability chromatography,and mechanical measurements.The experimental results indicated that the BCE-H200 catalyst had higher activity,more stable hydrogen response,and excellent copolymerization ability.Compared to the con-trol catalyst,the activity of the BCE-H200 catalyst was improved by 87.5%,resulting in a decrease in the hydrogen consumption by 12.5%and in the butene-1 consumption by 13.1%.The obtained PE-HD resin by using the BCE-H200 catalyst shows a large particle size,less fine particles,better mechanical properties,and less gel under a high load.Such performance can meet the production standard.The BCE-H200 catalyst can be used to replace the imported cata-lysts for producing the high-performance film-grade PE-HD resin.In addition,the evaluation on the gel from the control film indicated that the gel was composed of the PE with high molecular weight and low crystallinity.
