摘　　要：在中国石化茂名分公司国产第二代环管聚丙烯工艺装置上,采用国产球形Ziegler-Natta催化剂(催化剂1)生产了PPH-T03、N-Z30S和PPR-M55-S三种牌号聚丙烯。研究了球形催化剂在生产三种牌号聚丙烯时的催化剂效率和氢调性,同时分析了各牌号聚丙烯的粉料粒径及产品质量,并将其与另一个国产球形催化剂(催化剂2)进行了对比分析。实验结果表明,与催化剂2相比,两种催化剂生产的聚丙烯在产品质量上相当,但催化剂1的氢调性更加优异,更有利于装置生产高熔融指数产品。Three kinds of polypropylene(PPH-T03,N-Z30S and PPR-M55-S)were produced with domestic spherical Ziegler-Natta catalyst(Catalyst 1)in the second generation of Sinopec loop reactor polypropylene process of Sinopec Maoming Branch.The catalytic efficiency and hydrogen sensitivity of spherical catalyst for producing three kinds of polypropylene were studied.The particle size and product quality of each kind of polypropylene were analyzed and compared with another domestic spherical catalyst(Catalyst 2).The results show that the quality of polypropylene produced by the two catalysts is similar to that of Catalyst 2,but the hydrogen conditioning of Catalyst 1 is better,which is more advantageous to the production of high melt index products.
