摘　　要：采用BCND-Ⅱ催化剂在225 kt/a Novolen工艺聚丙烯(PP)装置上进行了工业应用试验,考察了该催化剂的各项性能及装置运行的平稳性、经济性及PP产品的质量。试验结果表明,与参比催化剂相比,在生产PP产品牌号为1102K、负荷18.5 t/h的工况下,BCND-Ⅱ催化剂的活性可达26.9 t/kg(基于每kg催化剂的PP产量),较参比催化剂高出约49%;工业装置运行平稳,聚合反应器温度控制稳定(温度标准偏差只有0.79,而参比催化剂的温度标准偏差为1.59);生产的PP产品符合用户优级品的质量要求,说明BCND-Ⅱ催化剂在Novolen工艺PP装置上进行工业应用是可行的。BCND-Ⅱcatalyst was applied industrially to a 225 kt/a Novolen propylene polymerization process to investigate the stability of the operation and the quality of the polypropylene（PP） product.The results indicated that the activity of BCND-Ⅱ catalyst reached 26.9 kg/g（PP yield based on per g catalyst）,49% higher than a reference catalyst in producing 1102K PP resin with 18.5 t/h.BCND-Ⅱ catalyst could be stable in this Novolen process,the standard deviation of polymeriz ation temperature was only 0.79 while that of the reference catalyst was 1.59.The 1102K PP product with high quality was produced.
