摘　　要：采用BCL-100催化剂，在中沙（天津）石化有限公司300kt／a的聚乙烯装置上进行生产PE100级管材专用料的工业试验。考察了催化剂的活性、氢调敏感性、共聚性能，并与参比催化剂进行对比。采用SEM技术观察催化剂和聚乙烯粉料的颗粒形态。表征结果显示，BCL-100催化剂的颗粒形态良好，粒径分布均匀集中，颗粒圆润密实，大颗粒和细粉含量较低；BCL-100催化剂制备的聚乙烯粉料颗粒形态优良，大于700μm的大颗粒和小于45μm细粉的含量极低，接近于0。试验结果表明，BCL—100催化剂的活性（以每克催化剂计）达到27-30kg／g，比参比催化剂的活性提高约80％；氢调敏感性和共聚性能优良；BCL-100催化剂制备的聚乙烯性能优于参比催化剂制备的聚乙烯。The industrial application of the BCL-100 catalyst for the polyethylene（PN049-030- 122LS） was carried out in the Innovene S process of SSTPC, and the adaptability of the catalyst to the process was investigated. The BCL-100 catalyst was compared with a reference catalyst in the process, and the properties of the resins produced with the two catalysts were invetigated. The experimental results showed that the BCL-100 catalyst was more adaptable and economic than the reference catalyst. The activity of the BCL-100 catalyst was 27-30 kg/g, which was about 80% higher than that of the reference catalyst. And, the abilities of hydrogen response and copolymerization of the BCL-100 catalyst were better than those of the reference catalyst. The particle morphology of the polymer produced with the BCL-100 catalysts was very nice. The polymer fines was mainly distributed in the range of 90-325 μm, and the contents of both the bigger than 700 μm particles and the less than 45 μm fines were close to 0.
