Abstract: Commercial trial on HDPE unit of 350 kt·a-1 Hostalen ACP process for producing ACP7000F film grade resin by BCE-H200 catalyst had been succeeded. Using melt flow rate (MFR), gel permeability chromatography (GPC) and mechanical tests to characterise general performance of catalyst, polyethylene (PE) powder and film resin. Tests result showed that BCE-H200 catalyst had higher activity, stabler hydrogen response and excellent copolymerisation ability. Compared to reference catalyst, the activity of BCE-H200 catalyst improved 87.5%, hydrogen consumption decreased 12.5%, butene-1 consumption decreased 13.1%, fines were less, and average particle size of its PE powder was bigger. Mechanical properties of film resin produced by BCE-H200 catalyst was better, less gel under high load, which met production standard of customer. Imported catalyst can be replaced by BCE-H200 catalyst for producing high performance film grade resin. Researching on gel from reference film showed that its content was PE of high molecular weight and low crystallinity.
